1
00:00:00,000 --> 00:00:08,000
Now installing software on the anonymous Unix cube is slightly different than installing software on

2
00:00:08,000 --> 00:00:15,000
the other virtual machines because the others were based on fedora and as we see in Fedora comes with

3
00:00:15,000 --> 00:00:17,000
its nice package installer.

4
00:00:17,000 --> 00:00:21,000
So if we go on the personal or on the work, they're all based on Fedora.

5
00:00:21,000 --> 00:00:28,000
So if we want to install something on any of them, we go to the Fedora Template and we click on software.

6
00:00:28,000 --> 00:00:34,000
This will launch a really nice graphical interface that allows us to install software and anything we

7
00:00:34,000 --> 00:00:39,000
install in here will become available to work, personal, untrusted and so on.

8
00:00:39,000 --> 00:00:47,000
Because they're all based on the fedora 30 now, because the Unix, because the non Unix and the disposable

9
00:00:47,000 --> 00:00:55,000
Unix that we use are based on the if you look in here, you'll see they're based on the UND X 15, you'll

10
00:00:55,000 --> 00:01:04,000
see that installing software on the x 15 is a little bit different than Fedora because it does not have

11
00:01:04,000 --> 00:01:07,000
a nice package manager and nice graphical interface.

12
00:01:07,000 --> 00:01:11,000
Therefore we're going to have to install software from terminal.

13
00:01:11,000 --> 00:01:13,000
Now, don't worry about this.

14
00:01:13,000 --> 00:01:14,000
I'm going to take you through it right now.

15
00:01:14,000 --> 00:01:20,000
If you've done any of my other courses, then this will be very easy and very familiar to you.

16
00:01:20,000 --> 00:01:24,000
But I still suggest you watch this lecture as you might learn a trick or two.

17
00:01:25,000 --> 00:01:29,000
Now, to do this, we're going to have to let me minimize this.

18
00:01:30,000 --> 00:01:34,000
We're going to have to go to the template that we want to install software on.

19
00:01:34,000 --> 00:01:39,000
And like I said, there is no graphical user interface that allows us to install software.

20
00:01:39,000 --> 00:01:42,000
Therefore we're going to have to do it from the terminal.

21
00:01:44,000 --> 00:01:44,000
Okay.

22
00:01:44,000 --> 00:01:46,000
Now, this will start a nice terminal for us.

23
00:01:46,000 --> 00:01:48,000
I'm just going to clear it screen.

24
00:01:48,000 --> 00:01:54,000
And the first thing that you want to do when you start this terminal is update the sources from which

25
00:01:54,000 --> 00:01:56,000
you can download packages and software.

26
00:01:57,000 --> 00:02:03,000
We need to do this with admin privileges, so to run a command with admin privileges, we have to first

27
00:02:03,000 --> 00:02:07,000
type sudo and then type the command that we want to run.

28
00:02:07,000 --> 00:02:11,000
And in my case, I want to update the sources, like I said.

29
00:02:11,000 --> 00:02:13,000
So the command will be up to get.

30
00:02:14,000 --> 00:02:15,000
Update.

31
00:02:16,000 --> 00:02:24,000
So update is the program that we use to install software on Debian based operating systems such as Linux.

32
00:02:24,000 --> 00:02:30,000
And what we want to do is literally just update the sources from which we can download software.

33
00:02:30,000 --> 00:02:32,000
We're not updating anything.

34
00:02:32,000 --> 00:02:36,000
We're literally just updating the list of packages that we can install.

35
00:02:37,000 --> 00:02:41,000
Once this is done, we can search for packages and install them.

36
00:02:42,000 --> 00:02:45,000
So let's say for example, you want to install pidgin.

37
00:02:45,000 --> 00:02:49,000
If you remember, we use pidgin before for instant messaging entails.

38
00:02:49,000 --> 00:02:52,000
So let's say you want to install this to do that.

39
00:02:52,000 --> 00:02:58,000
First of all, let's say you don't really remember the program name or you want to search because you're

40
00:02:58,000 --> 00:03:01,000
not sure what the name of the pidgin package.

41
00:03:01,000 --> 00:03:03,000
So let's say you want to search for this program.

42
00:03:03,000 --> 00:03:11,000
We're going to do sudo again and we're going to do apt catch and we're going to say i want to search

43
00:03:11,000 --> 00:03:13,000
for a package called pidgin.

44
00:03:15,000 --> 00:03:19,000
Now this will list all of the packages that has the word pigeon in them.

45
00:03:19,000 --> 00:03:22,000
So you'll see the package that you want.

46
00:03:22,000 --> 00:03:26,000
Plus a lot of other packages may be related, maybe not even related.

47
00:03:26,000 --> 00:03:31,000
So, for example, let's say you're looking for a chat program or a messaging program, you can just

48
00:03:31,000 --> 00:03:34,000
do a catch search message.

49
00:03:35,000 --> 00:03:39,000
In my example, as you can see right here, I have the name of the package that I want to install or

50
00:03:39,000 --> 00:03:41,000
the name of the program pigeon.

51
00:03:41,000 --> 00:03:46,000
And I also have the description of it, which is a graphical multi protocol instant messaging client.

52
00:03:47,000 --> 00:03:51,000
So all I need to do is basically install a package called pigeon.

53
00:03:52,000 --> 00:03:57,000
Now to do that again, we're going to do pseudo because we need to run this under admin.

54
00:03:57,000 --> 00:04:03,000
We're going to use the same program update and instead of updating the sources, we're going to say,

55
00:04:03,000 --> 00:04:06,000
I want to install a program called Pigeon.

56
00:04:07,000 --> 00:04:09,000
Very, very simple.

57
00:04:09,000 --> 00:04:10,000
We're going to hit enter.

58
00:04:11,000 --> 00:04:16,000
And because I've actually downloaded and installed this before, it's automatically downloaded and install

59
00:04:16,000 --> 00:04:18,000
it for me without asking me.

60
00:04:18,000 --> 00:04:23,000
But for you, if you're installing software or a package for the first time, it's going to ask you

61
00:04:23,000 --> 00:04:28,000
to confirm and you're just going to have to type Y and hit enter to continue the process.

62
00:04:29,000 --> 00:04:36,000
Now, once this is done, pigeon's installed now on my template virtual machine, my UNIX workstation

63
00:04:36,000 --> 00:04:36,000
15.

64
00:04:36,000 --> 00:04:41,000
Like I said, we never use the templates to run the actual software.

65
00:04:41,000 --> 00:04:44,000
We only use them if we want to update or install software.

66
00:04:44,000 --> 00:04:46,000
So this is done, this is installed.

67
00:04:46,000 --> 00:04:47,000
We're happy with it.

68
00:04:47,000 --> 00:04:52,000
I'm going to close it and I'm going to shut down my UNIX workstation.

69
00:04:54,000 --> 00:04:56,000
And wait for it to fully shut down.

70
00:04:56,000 --> 00:05:01,000
And once it is off, I'm going to go to my cubes manager again.

71
00:05:01,000 --> 00:05:05,000
I'm going to go to the machine that I want to use the program from.

72
00:05:05,000 --> 00:05:10,000
So, for example, the anon x right here, we're going to go to its settings so it can click on this

73
00:05:10,000 --> 00:05:13,000
or we can right click and go to settings.

74
00:05:14,000 --> 00:05:20,000
We're going to go to applications and as you can see, we have the pigeon instance manager available

75
00:05:20,000 --> 00:05:21,000
for us in here.

76
00:05:21,000 --> 00:05:25,000
Now you want to make sure that the machine is off when you're doing this.

77
00:05:25,000 --> 00:05:26,000
Otherwise you won't see it.

78
00:05:26,000 --> 00:05:32,000
If you don't see it, try to click on refresh applications and it should become available.

79
00:05:33,000 --> 00:05:37,000
Now, once we have it, we're going to click on it here to make it available in the dropdown menu in

80
00:05:37,000 --> 00:05:40,000
here and we're going to click on okay.

81
00:05:40,000 --> 00:05:49,000
So now I can go in here and I can go to my and on UNIX and I have pigeon instant messenger right here

82
00:05:49,000 --> 00:05:55,000
so I can click on it, wait for the virtual machine to start and it will start paging for me once the

83
00:05:55,000 --> 00:05:58,000
virtual machine is working and perfect.

84
00:05:58,000 --> 00:06:05,000
As you can see now I have pigeon working inside my an on next domain and we can use it exactly the same

85
00:06:05,000 --> 00:06:07,000
that we learned with tails.

86
00:06:07,000 --> 00:06:12,000
We click on ADD, you create your user or your login to your existing account and then you start communicating,

87
00:06:12,000 --> 00:06:14,000
sending messages and so on.

88
00:06:15,000 --> 00:06:21,000
Now in this example, obviously I literally just installed Pigeon, but you can follow the exact same

89
00:06:21,000 --> 00:06:25,000
steps if you want to install any other program or any other package.

90
00:06:27,000 --> 00:06:32,000
Now I highly recommend you get comfortable with using the terminal and installing programs through the

91
00:06:32,000 --> 00:06:33,000
terminal through APT Gate.

92
00:06:33,000 --> 00:06:40,000
But if you really want to have an easy way of installing programs, a graphical user interface, then

93
00:06:40,000 --> 00:06:47,000
you can install a program called Synaptic which basically interacts with APT Gate and allows you to

94
00:06:47,000 --> 00:06:53,000
install software through a nice graphical user interface, similar to what we did when we were installing

95
00:06:53,000 --> 00:06:56,000
programs inside the Fedora 30 virtual machine.

96
00:06:57,000 --> 00:07:03,000
Now to do this, we'll have to install synaptic, we'll have to install this graphical interface.

97
00:07:03,000 --> 00:07:11,000
So let me turn off my UNIX machine again and we're going to go back to the terminal of our template,

98
00:07:11,000 --> 00:07:16,000
which is the UNIX workstation and we're going to clear the screen.

99
00:07:16,000 --> 00:07:23,000
And this time instead of doing APT get installed pigeon, we're going to install a program called Synaptic.

100
00:07:24,000 --> 00:07:25,000
We're going to hit enter.

101
00:07:26,000 --> 00:07:28,000
It's asking me if I really want to do this.

102
00:07:28,000 --> 00:07:31,000
I'm going to say yes, please install it for me.

103
00:07:31,000 --> 00:07:37,000
And like I said, this is literally just a graphical user interface that allows us to install packages

104
00:07:37,000 --> 00:07:39,000
if you really don't want to use the terminal.

105
00:07:40,000 --> 00:07:40,000
Perfect.

106
00:07:40,000 --> 00:07:46,000
Now it's installed and usually we don't use any programs inside the template.

107
00:07:46,000 --> 00:07:47,000
Virtual machines.

108
00:07:47,000 --> 00:07:49,000
Like I said, we use them inside the domains.

109
00:07:49,000 --> 00:07:52,000
This is what we did literally with pigeon and with everything else.

110
00:07:52,000 --> 00:07:58,000
But because synaptic, the program that we installed is a program that allows us to install other packages

111
00:07:58,000 --> 00:08:04,000
and other programs, it only makes sense to use it inside the template so that all of the other virtual

112
00:08:04,000 --> 00:08:08,000
machines that are based on this template would inherit these programs.

113
00:08:08,000 --> 00:08:13,000
Therefore, we'd want to use this inside our template virtual machine.

114
00:08:13,000 --> 00:08:20,000
So back to the queue manager, we're going to select our template, which is the UNIX Workstation 15.

115
00:08:20,000 --> 00:08:22,000
We're going to go to its settings.

116
00:08:23,000 --> 00:08:24,000
Applications.

117
00:08:24,000 --> 00:08:26,000
We're going to scroll down.

118
00:08:26,000 --> 00:08:29,000
We're going to look for the package manager.

119
00:08:29,000 --> 00:08:31,000
We're going to add it here to the right.

120
00:08:31,000 --> 00:08:33,000
We're going to click on OC.

121
00:08:33,000 --> 00:08:40,000
And now if we go to the dropdown menu over in here, you'll see we have a new entry which will allow

122
00:08:40,000 --> 00:08:45,000
us to launch this graphical interface for the package manager for APT Get.

123
00:08:46,000 --> 00:08:49,000
We're going to close this warning and perfect.

124
00:08:49,000 --> 00:08:54,000
As you can see, we have a program that has a nice graphical user interface.

125
00:08:54,000 --> 00:09:00,000
You can use the search button in here to search and then if you want to install any package, you literally

126
00:09:00,000 --> 00:09:02,000
just tick it in here from the list.

127
00:09:02,000 --> 00:09:10,000
Mark for installation and mark and then click on apply to apply the changes and install the package.

128
00:09:10,000 --> 00:09:14,000
Like I said, I highly recommend getting used to using the terminal.

129
00:09:14,000 --> 00:09:19,000
It is much better and if you know how to use it, you can use it across multiple platforms.

130
00:09:19,000 --> 00:09:23,000
You're also installing less packages so there is less attack surface.

131
00:09:23,000 --> 00:09:28,000
And finally, there are people reporting issues with synaptic inside UNIX.

132
00:09:28,000 --> 00:09:30,000
They're saying it creates a lot of problems.

133
00:09:30,000 --> 00:09:34,000
So you can see whatever is due to best and just go with it.

134
00:09:34,000 --> 00:09:37,000
Now, finally, before we wrap this up, I'm going to close this.

135
00:09:37,000 --> 00:09:38,000
I'm going to quit.

136
00:09:38,000 --> 00:09:43,000
I just want to show you how you would update any virtual machine or any template.

137
00:09:44,000 --> 00:09:49,000
I've touched on it before, so you can actually start the template, whether it's a fedora or Debian

138
00:09:49,000 --> 00:09:51,000
or even if it's another operating system.

139
00:09:51,000 --> 00:09:55,000
Literally look up how that operating system gets updated and follow the steps.

140
00:09:55,000 --> 00:10:02,000
So usually for Linux you do apt get update, apt get upgrade and then apt get dist upgrade to upgrade

141
00:10:02,000 --> 00:10:04,000
for another distro if there is a new release.

142
00:10:05,000 --> 00:10:10,000
Alternatively, you can actually just do it in here from your cubes manager for example.

143
00:10:10,000 --> 00:10:16,000
Again, let's say you want to update your UNIX workstation, right click, click on update.

144
00:10:16,000 --> 00:10:19,000
This will automatically start the virtual machine if it's off.

145
00:10:19,000 --> 00:10:21,000
In my case it was already on.

146
00:10:21,000 --> 00:10:27,000
It will start the terminal, it will check the sources and once it gets a list of all the updates,

147
00:10:27,000 --> 00:10:34,000
all you have to do in here, it's asking us to confirm you hit y hit enter and it will update it for

148
00:10:34,000 --> 00:10:34,000
you.
