I use Lubuntu 12.04 and have tried to install lubuntu-restricted-extras in Synaptic.

It seemed stuck at one point: when asked to accept some Microsoft EULA for fonts (I guess), I hit Enter and it seemed to me that I could not do anything but try to shut down synaptic, which I could not do and finally logged out.

Maybe I should not have done that but that is what I did.

After logging in and then after reboot, no installation would start, as if Synaptic was still working.

The problem seems to be with the installation of lubuntu-restricted-extras being incomplete.

What is it to be done?

When I type

 sudo dpkg --configure -a

I get:

dpkg: error: dpkg status database is locked by another process

I found here that I could type

sudo rm /var/lib/dpkg/lock


 sudo dpkg --configure -a

and then update (works ok) and upgrade, at which point I get

$ sudo apt-get upgrade

Synaptic can be opened, which did not happened before. But when I try to install lubuntu-restricted-extras in synaptic I get this:

Did you try using the tab key to highlight the Accept button when you asked to accept the EULA? – Aaron Hill Aug 21 '12 at 11:07
no, i just hit enter... so it seemed stuck to me and I interrupted the installation by logging out!... – cipricus Aug 21 '12 at 11:09… that seems to have helped – cipricus Aug 21 '12 at 11:55
@cipricus - You can post the above linked solution here and accept your own answer , that would help other users with same problem, Thanks :) – atenz Aug 21 '12 at 14:18

The problem is close to this one and to others that now I don't seem able to find here. I will re-edit when I 'll find them.

It is a bug it looks like, and the solution consists in typing

sudo rm -rf /var/cache/debconf/*
sudo apt-get install -f

which seems to resume the broken installation. I had some errors but then I was able to make installations.

The full upgrade involved some errors that only a partial upgrade is possible, but the interrupted installation seems to have been resolved during this upgrade (including that Microsoft EULA that was again presented to me -- see comments to the question) and after that, and a reboot, things look fine.
