1
00:00:01,640 --> 00:00:06,180
Packages can be uninstalled using either the high level or low level tools.

2
00:00:06,200 --> 00:00:12,560
So in debian we will use the package management apt aptitude here.

3
00:00:12,830 --> 00:00:13,520
APT.

4
00:00:14,510 --> 00:00:17,570
Get remove and package name.

5
00:00:17,570 --> 00:00:23,750
So you will enter the package name after that name.

6
00:00:24,600 --> 00:00:29,710
Uh, so we can also install the package by using the dpkg as we learned earlier.

7
00:00:29,730 --> 00:00:30,870
Dpkg here.

8
00:00:30,870 --> 00:00:33,990
And after that you will enter the instead of package name you need.

9
00:00:34,140 --> 00:00:38,160
If you are entering the dpkg you will enter the package file.

10
00:00:38,280 --> 00:00:43,960
So and in red hat it's going to be rpm and package file again.

11
00:00:43,980 --> 00:00:45,260
Package file.

12
00:00:45,270 --> 00:00:52,830
So for example, if we if you want to enter the Google Chrome, you will in RPM and the file had been

13
00:00:52,830 --> 00:01:00,750
downloaded from a run repository file, it will be installed like that way here E and Google Google

14
00:01:00,750 --> 00:01:06,100
dot RPM or Google Chrome dot rpm.

15
00:01:06,120 --> 00:01:07,830
And for the.

16
00:01:08,810 --> 00:01:12,120
Ubuntu or ubuntu like debian like systems.

17
00:01:12,140 --> 00:01:13,880
It's going to be dpkg.

18
00:01:15,230 --> 00:01:15,940
DPG.

19
00:01:17,490 --> 00:01:18,030
E here.

20
00:01:18,030 --> 00:01:23,430
And after that you will enter the file that you installed specifically for Debian based systems apt

21
00:01:23,460 --> 00:01:23,700
here.

22
00:01:23,700 --> 00:01:26,520
So in this case it's going to be the.

23
00:01:28,140 --> 00:01:30,480
Chrome or Google Chrome.

24
00:01:30,780 --> 00:01:34,110
Google Chrome dot deb here.

25
00:01:34,200 --> 00:01:40,350
So mostly it's a deb file, but there's also another file extensions for that and for removing packages

26
00:01:40,350 --> 00:01:45,680
and packages can be installed using either the high level or low level tools, as I said earlier.

27
00:01:45,690 --> 00:01:52,200
So for Debian you can also use the sudo if you have problems with permissions and etcetera.

28
00:01:52,200 --> 00:01:57,990
But here apt get remove and after that you will enter the package name.

29
00:01:59,620 --> 00:02:03,010
And instead of a ticket you can also use APT alone.

30
00:02:03,010 --> 00:02:05,380
But it's your choice.

31
00:02:05,560 --> 00:02:08,230
And here, as you can see here, the permission denied.

32
00:02:08,230 --> 00:02:13,430
So I will enter the sudo to use the superuser and signs it will.

33
00:02:13,720 --> 00:02:16,750
There will be no package like package name.

34
00:02:16,750 --> 00:02:17,890
It will do nothing here.

35
00:02:25,360 --> 00:02:26,080
Here, let me.

36
00:02:32,340 --> 00:02:34,170
As I enter the password.

37
00:02:40,250 --> 00:02:40,670
Okay.

38
00:02:41,410 --> 00:02:48,730
So, for example, if you want to remove the Google Chrome, you will enter the APT get remove the Google

39
00:02:48,730 --> 00:02:54,070
Chrome here and it will remove your Google Chrome application that you installed previously in your

40
00:02:54,070 --> 00:02:55,270
system here.

41
00:02:55,270 --> 00:02:58,300
And as you can see, unable to locate the Google Chrome.

42
00:02:58,390 --> 00:03:03,280
That's because the Google Chrome is not installed and this is not a proper Google Chrome package name.

43
00:03:03,280 --> 00:03:04,030
It's the Google Chrome.

44
00:03:04,030 --> 00:03:06,940
Is something like that A Chrome.

45
00:03:07,720 --> 00:03:09,700
And version name like this.

46
00:03:10,090 --> 00:03:12,940
So you can also update the packages from a repository.

47
00:03:13,030 --> 00:03:18,460
And the most common package management task is keeping the system up to date with the latest versions

48
00:03:18,460 --> 00:03:19,450
of packages.

49
00:03:19,450 --> 00:03:23,510
The high level tools can perform this vital task in a single step.

50
00:03:23,530 --> 00:03:34,300
This apt get update and actually we can also sudo apt get update and apt After that you can also write

51
00:03:34,330 --> 00:03:38,050
apt get upgrade which here.

52
00:03:38,050 --> 00:03:42,040
Now we're going to update the repositories right here after that.

53
00:04:05,610 --> 00:04:06,510
I think it's done.

54
00:04:13,840 --> 00:04:18,160
So after that you will enter the apt get upgrade.

55
00:04:18,250 --> 00:04:24,550
And here we also need to use the sudo command right here and here it will update.

56
00:04:24,550 --> 00:04:29,440
So after this operation, 149MB disk space will be freed.

57
00:04:30,160 --> 00:04:30,940
Yes.

58
00:04:31,650 --> 00:04:38,160
And here, as you can see, we upgrading our packages that we updated previously, we updated our repositories

59
00:04:38,160 --> 00:04:41,400
and then we upgrading our packages and programs.

60
00:04:41,400 --> 00:04:48,000
So, for example, to apply all available updates, updates to be installed packages on the Debian style,

61
00:04:48,000 --> 00:04:52,680
we can use the upgrade in order to do this process here.

62
00:04:54,200 --> 00:04:54,980
As you can see here.

63
00:04:54,980 --> 00:05:00,410
Now I'm updating some modules, some libraries, Python three libraries.

64
00:05:01,560 --> 00:05:05,370
Here are some network managers and etcetera.

65
00:05:05,370 --> 00:05:06,780
So I will cut this here.

66
00:05:08,430 --> 00:05:09,960
I will update it later.

67
00:05:09,960 --> 00:05:11,400
And we can also.

68
00:05:12,710 --> 00:05:14,270
A list of installed packages here.

69
00:05:14,270 --> 00:05:16,020
So here.

70
00:05:16,040 --> 00:05:24,770
Dpkg l will list you the installed packages so you can use and navigate with a key arrow keys here.

71
00:05:24,770 --> 00:05:27,320
So here as you can see here.

72
00:05:28,500 --> 00:05:29,550
Uh, actually, let's.

73
00:05:29,550 --> 00:05:32,010
Let's write this command again.

74
00:05:32,490 --> 00:05:40,770
Dpkg l dpkg l for the debian base and rpm q a for redhat here.

75
00:05:40,770 --> 00:05:48,900
So in this case my system is debian and here dpkg and as you can see here we have the package names,

76
00:05:48,900 --> 00:05:53,280
their descriptions, their architecture and their versions.

77
00:05:57,750 --> 00:05:58,830
Here, as you can see here.

78
00:05:58,830 --> 00:05:59,370
Faridi.

79
00:05:59,370 --> 00:06:01,020
Quli Faridi agent.

80
00:06:01,050 --> 00:06:05,490
These are some pentester tools that we will use later.

81
00:06:05,520 --> 00:06:07,890
GCC for compilation.

82
00:06:11,450 --> 00:06:12,680
And etcetera.

83
00:06:17,280 --> 00:06:21,780
And we can also determine whether a package installed or not.

84
00:06:21,780 --> 00:06:25,470
So in order to do that, we will use S here.

85
00:06:25,470 --> 00:06:34,050
So for RedHat based systems, it's going to be RPM and after that package name for Debian, it's going

86
00:06:34,050 --> 00:06:38,370
to be dpkg s and our package for ready here.

87
00:06:38,370 --> 00:06:42,660
And as you can see here, a package paradise is installed.

88
00:06:42,660 --> 00:06:43,020
Okay.

89
00:06:43,020 --> 00:06:50,520
Installed priority optional section for python and maintainer are kali developers architecture all and

90
00:06:50,520 --> 00:06:58,620
python for so for example to determine whether the for example to determine where the python.

91
00:07:00,530 --> 00:07:03,150
Where the python is exist or not.

92
00:07:03,170 --> 00:07:05,270
We can also do Python three.

93
00:07:06,020 --> 00:07:09,140
And here, as you can see here, package python install.

94
00:07:09,170 --> 00:07:13,280
Okay installed optional Python installed size 7 to 9.

95
00:07:13,310 --> 00:07:19,400
Matthias Close architecture, Multiarch source and etcetera.

96
00:07:19,400 --> 00:07:24,770
And there's also a little description for our program, interactive high level object oriented language

97
00:07:24,770 --> 00:07:26,360
default Python three versions Python.

98
00:07:26,360 --> 00:07:32,000
The high level interactive object oriented language includes extensive class library with a lot of goodies

99
00:07:32,000 --> 00:07:37,130
for network programming system administration sounds and graphics and.

100
00:07:38,220 --> 00:07:40,980
Now let's actually find which package.

101
00:07:40,980 --> 00:07:43,010
Um, installed a file.

102
00:07:43,020 --> 00:07:48,390
So in order to determine what packages are responsible for the installation of a particular file, we

103
00:07:48,390 --> 00:08:02,250
can use the command dpkg uppercase s and for the red hat we can use rpm, q, a lowercase q and lowercase

104
00:08:02,250 --> 00:08:05,550
f, and after that you will enter the file name.

105
00:08:07,170 --> 00:08:13,680
So in this section of our course, we will we explore the main different programs covered a wide range

106
00:08:13,680 --> 00:08:14,870
of applications areas.

107
00:08:14,900 --> 00:08:20,010
And while most of these programs are commonly installed by default and we may need to install additional

108
00:08:20,010 --> 00:08:24,570
packages if the necessary programs are not installed on our system.

109
00:08:24,660 --> 00:08:31,500
So without newfound knowledge and appreciation of package management, we should have no problem installing

110
00:08:31,500 --> 00:08:33,720
and managing the programs we need.
