WEBVTT 00:01.640 --> 00:06.180 Packages can be uninstalled using either the high level or low level tools. 00:06.200 --> 00:12.560 So in debian we will use the package management apt aptitude here. 00:12.830 --> 00:13.520 APT. 00:14.510 --> 00:17.570 Get remove and package name. 00:17.570 --> 00:23.750 So you will enter the package name after that name. 00:24.600 --> 00:29.710 Uh, so we can also install the package by using the dpkg as we learned earlier. 00:29.730 --> 00:30.870 Dpkg here. 00:30.870 --> 00:33.990 And after that you will enter the instead of package name you need. 00:34.140 --> 00:38.160 If you are entering the dpkg you will enter the package file. 00:38.280 --> 00:43.960 So and in red hat it's going to be rpm and package file again. 00:43.980 --> 00:45.260 Package file. 00:45.270 --> 00:52.830 So for example, if we if you want to enter the Google Chrome, you will in RPM and the file had been 00:52.830 --> 01:00.750 downloaded from a run repository file, it will be installed like that way here E and Google Google 01:00.750 --> 01:06.100 dot RPM or Google Chrome dot rpm. 01:06.120 --> 01:07.830 And for the. 01:08.810 --> 01:12.120 Ubuntu or ubuntu like debian like systems. 01:12.140 --> 01:13.880 It's going to be dpkg. 01:15.230 --> 01:15.940 DPG. 01:17.490 --> 01:18.030 E here. 01:18.030 --> 01:23.430 And after that you will enter the file that you installed specifically for Debian based systems apt 01:23.460 --> 01:23.700 here. 01:23.700 --> 01:26.520 So in this case it's going to be the. 01:28.140 --> 01:30.480 Chrome or Google Chrome. 01:30.780 --> 01:34.110 Google Chrome dot deb here. 01:34.200 --> 01:40.350 So mostly it's a deb file, but there's also another file extensions for that and for removing packages 01:40.350 --> 01:45.680 and packages can be installed using either the high level or low level tools, as I said earlier. 01:45.690 --> 01:52.200 So for Debian you can also use the sudo if you have problems with permissions and etcetera. 01:52.200 --> 01:57.990 But here apt get remove and after that you will enter the package name. 01:59.620 --> 02:03.010 And instead of a ticket you can also use APT alone. 02:03.010 --> 02:05.380 But it's your choice. 02:05.560 --> 02:08.230 And here, as you can see here, the permission denied. 02:08.230 --> 02:13.430 So I will enter the sudo to use the superuser and signs it will. 02:13.720 --> 02:16.750 There will be no package like package name. 02:16.750 --> 02:17.890 It will do nothing here. 02:25.360 --> 02:26.080 Here, let me. 02:32.340 --> 02:34.170 As I enter the password. 02:40.250 --> 02:40.670 Okay. 02:41.410 --> 02:48.730 So, for example, if you want to remove the Google Chrome, you will enter the APT get remove the Google 02:48.730 --> 02:54.070 Chrome here and it will remove your Google Chrome application that you installed previously in your 02:54.070 --> 02:55.270 system here. 02:55.270 --> 02:58.300 And as you can see, unable to locate the Google Chrome. 02:58.390 --> 03:03.280 That's because the Google Chrome is not installed and this is not a proper Google Chrome package name. 03:03.280 --> 03:04.030 It's the Google Chrome. 03:04.030 --> 03:06.940 Is something like that A Chrome. 03:07.720 --> 03:09.700 And version name like this. 03:10.090 --> 03:12.940 So you can also update the packages from a repository. 03:13.030 --> 03:18.460 And the most common package management task is keeping the system up to date with the latest versions 03:18.460 --> 03:19.450 of packages. 03:19.450 --> 03:23.510 The high level tools can perform this vital task in a single step. 03:23.530 --> 03:34.300 This apt get update and actually we can also sudo apt get update and apt After that you can also write 03:34.330 --> 03:38.050 apt get upgrade which here. 03:38.050 --> 03:42.040 Now we're going to update the repositories right here after that. 04:05.610 --> 04:06.510 I think it's done. 04:13.840 --> 04:18.160 So after that you will enter the apt get upgrade. 04:18.250 --> 04:24.550 And here we also need to use the sudo command right here and here it will update. 04:24.550 --> 04:29.440 So after this operation, 149MB disk space will be freed. 04:30.160 --> 04:30.940 Yes. 04:31.650 --> 04:38.160 And here, as you can see, we upgrading our packages that we updated previously, we updated our repositories 04:38.160 --> 04:41.400 and then we upgrading our packages and programs. 04:41.400 --> 04:48.000 So, for example, to apply all available updates, updates to be installed packages on the Debian style, 04:48.000 --> 04:52.680 we can use the upgrade in order to do this process here. 04:54.200 --> 04:54.980 As you can see here. 04:54.980 --> 05:00.410 Now I'm updating some modules, some libraries, Python three libraries. 05:01.560 --> 05:05.370 Here are some network managers and etcetera. 05:05.370 --> 05:06.780 So I will cut this here. 05:08.430 --> 05:09.960 I will update it later. 05:09.960 --> 05:11.400 And we can also. 05:12.710 --> 05:14.270 A list of installed packages here. 05:14.270 --> 05:16.020 So here. 05:16.040 --> 05:24.770 Dpkg l will list you the installed packages so you can use and navigate with a key arrow keys here. 05:24.770 --> 05:27.320 So here as you can see here. 05:28.500 --> 05:29.550 Uh, actually, let's. 05:29.550 --> 05:32.010 Let's write this command again. 05:32.490 --> 05:40.770 Dpkg l dpkg l for the debian base and rpm q a for redhat here. 05:40.770 --> 05:48.900 So in this case my system is debian and here dpkg and as you can see here we have the package names, 05:48.900 --> 05:53.280 their descriptions, their architecture and their versions. 05:57.750 --> 05:58.830 Here, as you can see here. 05:58.830 --> 05:59.370 Faridi. 05:59.370 --> 06:01.020 Quli Faridi agent. 06:01.050 --> 06:05.490 These are some pentester tools that we will use later. 06:05.520 --> 06:07.890 GCC for compilation. 06:11.450 --> 06:12.680 And etcetera. 06:17.280 --> 06:21.780 And we can also determine whether a package installed or not. 06:21.780 --> 06:25.470 So in order to do that, we will use S here. 06:25.470 --> 06:34.050 So for RedHat based systems, it's going to be RPM and after that package name for Debian, it's going 06:34.050 --> 06:38.370 to be dpkg s and our package for ready here. 06:38.370 --> 06:42.660 And as you can see here, a package paradise is installed. 06:42.660 --> 06:43.020 Okay. 06:43.020 --> 06:50.520 Installed priority optional section for python and maintainer are kali developers architecture all and 06:50.520 --> 06:58.620 python for so for example to determine whether the for example to determine where the python. 07:00.530 --> 07:03.150 Where the python is exist or not. 07:03.170 --> 07:05.270 We can also do Python three. 07:06.020 --> 07:09.140 And here, as you can see here, package python install. 07:09.170 --> 07:13.280 Okay installed optional Python installed size 7 to 9. 07:13.310 --> 07:19.400 Matthias Close architecture, Multiarch source and etcetera. 07:19.400 --> 07:24.770 And there's also a little description for our program, interactive high level object oriented language 07:24.770 --> 07:26.360 default Python three versions Python. 07:26.360 --> 07:32.000 The high level interactive object oriented language includes extensive class library with a lot of goodies 07:32.000 --> 07:37.130 for network programming system administration sounds and graphics and. 07:38.220 --> 07:40.980 Now let's actually find which package. 07:40.980 --> 07:43.010 Um, installed a file. 07:43.020 --> 07:48.390 So in order to determine what packages are responsible for the installation of a particular file, we 07:48.390 --> 08:02.250 can use the command dpkg uppercase s and for the red hat we can use rpm, q, a lowercase q and lowercase 08:02.250 --> 08:05.550 f, and after that you will enter the file name. 08:07.170 --> 08:13.680 So in this section of our course, we will we explore the main different programs covered a wide range 08:13.680 --> 08:14.870 of applications areas. 08:14.900 --> 08:20.010 And while most of these programs are commonly installed by default and we may need to install additional 08:20.010 --> 08:24.570 packages if the necessary programs are not installed on our system. 08:24.660 --> 08:31.500 So without newfound knowledge and appreciation of package management, we should have no problem installing 08:31.500 --> 08:33.720 and managing the programs we need.
