I'm a real newbie when it comes to whole Linux world. I've been using ubuntu 12.04 / 12.10 for a month or two and after some strange errors I started using Mint and I have been really satisfied with it.
A week ago, I tried to update Linux Mint 14 using update manager app, as I do usually once a week, but this time an error showed up:
E: apt: subprocess installed post-installation script returned error exit status 1
This is what I got in terminal (when I clicked on "details" in error message window):
Code: Select all
Setting up apt (0.9.7.5ubuntu5.4) ...
ERROR: Can't find the archive-keyring
Is the ubuntu-keyring package installed?
dpkg: error processing apt (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
apt
W: Waited for dpkg --assert-multi-arch but it wasn't there - dpkgGo (10: No child processes)
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install. Trying to recover:
Setting up apt (0.9.7.5ubuntu5.4) ...
ERROR: Can't find the archive-keyring
Is the ubuntu-keyring package installed?
dpkg: error processing apt (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
apt
I get the same error when I try to install or remove something.
I tried to use command apt get -f install but it didn't work.
Yesterday (and today, also) I tried to install Cinnamon, fsgamer (app that lets you minimize games in fullcreen), sublime text 2 and some other apps, nothing worked.
Strange thing, I installed BleachBit two days ago with no problems.
What should I do? I feel hopeless.
