Why does apt-get install python3 with a trailing hyphen remove a lot of packages? [duplicate]
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;

While is was installing something with the sudo apt-get install
command I accidentally accepted the command
sudo apt-get install python3-
(yeah I know it is stupid to just accept this but I did a lot of those and i just continued to click y
).
By executing the command I deleted my whole visual desktop of Ubuntu (I just had the plain shell but I recovered the visual desktop by now). I don't know if I am just stupid but nevertheless I want to create awareness that you shouldn't use the command.
If you can explain to me why happened what happened feel free to explain it to me.

@Scot I agree with you. Since there is already a dedicated command to remove packages I don't see the need for this feature. Seems like somebody wanted to include a "pro feature" that hurts new users and provides basically 0 value... The only case in which it would be useful is when you want to remove a package but your hand typesinstall
anyway and you realize at the end... but does this happen often enough to justify this feature? I don't think so.

This is not a bug; this is documented in the man
page. From man apt-get
's install
section1 (emphasis mine):
If a hyphen is appended to the package name (with no intervening space), the identified package will be removed if it is installed. Similarly a plus sign can be used to designate a package to install.
So, when you did:
sudo apt-get install python3-
you've removed the python3
package and all the dependent packages (which includes the packages you mentioned).
Fix:
Firstly, you can install the ubuntu-desktop
metapackage to get the default desktop environment back:
sudo apt-get install ubuntu-desktop
Now, to re-install the removed packages, go to /var/log/apt/history.log
, pick the packages, and run sudo apt-get install
on them.
You might also want to peek into /var/log/dpkg.log
.
1 If you have less
as the man
pager, you can go to the install
section of man apt-get
directly:
LESS='+/^[[:blank:]]+install' man apt-get
6
It might be worth mentioning thatsudo apt-get install ubuntu-desktop
will get most of the desktop environment back with a single command, without needing to hunt down individual package names. (Of course that doesn't cover whatever one has installed manually on top of the defaults, but further recovery can proceed in an environment that may be more familiar than the Linux console).
