I've looked at an aptitude tutorial and read the man page, but I just don't get it. After you launch aptitude, how do you say "install package foo"? Or search for all packages with "foo" in their name?
After running aptitude, use these key commands as found at Using aptitude GUI style: (If you use Bionic, use CTRL+T instead of F10)
F10 to access the aptitude menu.
? this is to access "help"
Use 'up' ↑, 'down' ↓ , 'left' ←, 'right' →, to navigate.
Use Enter to select items.
Use + or - to install, update, or remove a package
Use g to preview or confirm actions
q to quit – this will also close the currently open window (g goes forward, q goes back)
The common use of aptitude in TUI (text user interface) is:
- run aptitude;
- press u (update the lists of available packages);
- press U (Mark all upgradable packages to be upgraded);
- (search/select some stuff to install, is optional);
- press g (to see the pending actions and modify if needed);
- press g (again, to start the download).
Some time when you need to resolve conflicts, you discover that you made a mistake;
you can easily use 'Cancel pending actions' in the 'Actions' menu so that you can re-select.
When reviewing pending actions:
a explicitly accepts an action (use again to unaccept)
r rejects an action
g again goes ahead with pending actions
Using aptitude from the command line like apt-get
To install a package on a console run:
aptitude install package name
To search packages:
aptitude search package name
For example, let's say you want to install Pidgin
aptitude search pidgin
aptitude install pidgin
To search for a package, hit
/ and enter a part of the package name you want to search (regexps can be used). This is similar to search in editors like vim.
You can use the up- and down-arrow keys for browsing, together with enter for toggling the tree nodes.
When you have found the right package, hit
+ to mark it for installation (it will be shown in green and you see an
i as the second character in the status column). Then type
g (for "go") to get to the preview screen showing all pending changes. A second
g will start the installation.
You can also use enter when on a package to open a window with details of the package.
When there are more than one windows open in aptitude (like the package details and preview windows), you switch between them with
F7, and close the current window with
aptitude you can use the ncurses based console in the terminal (see the other answers for that) or use all of its options on the command line. I usually use the latter method, as I'll demonstrate using the example of the
(Before using any of the
aptitude install commands in this article it is worth running
sudo aptitude update to refresh the list of available software.)
To search for a package, use
aptitude search cheese
Then to show all the package information concerning versions and dependencies, type
aptitude show cheese
Then to install it use
sudo aptitude install cheese
However, beyond the standard basic usage of searching, removing, and installing packages,
aptitude can install and remove packages with one command. With
aptitude install commands add
- after the package name to have it removed, and with aptitude remove commands add
+ after the package name to have it installed.
If you enter
sudo aptitude install cheese gthumb-
cheese will be installed while
gthumb will be removed.
However, on the other hand, if you use
sudo aptitude remove grsync+ htop
htop will be removed and
