Unable to extract 7z archive

First time linux user here. Just installed Mint 14 KDE & unable to extract all 7z archives. Any tips will be very much appreciated. Thanks in advance.

Linux Mint is funded by ads and donations.

To clarify; you are able to extract some 7z archives, but not some others? is there anything special about those, like do they have a password or something?

None of the .7z files can be extracted at all. ZIP files extracted fine though. All archive files was created in WinXP with 7-zip.

Okay, gotcha :) Seems 7z support is not preloaded on the KDE version, but you can easily fix that. Install the package p7zip-full to add full support for 7z files. Either use Software Manager or Synaptic to install it, or do:
Code: Select all
apt install p7zip-full

Below is the output from the console :-
Code: Select all
phoebe@phoebe-ThinkPad-T60 /media/280GB $ apt install p7zip-full
[sudo] password for phoebe:
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package p7zip-full is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Another thing which I think might be ralated is that the 'Update Manager' seems to have some problem retrieving packages from the source as it shows the error below :-

Some index files failed to download. They have been ignored, or old ones used instead.

Something is wrong with your repositories, with you using the Linux Mint release name on the Ubuntu repositories (those expect a Ubuntu release name). The following command should correct this:
Code: Select all
sudo sed -i 's/nadia/quantal/' /etc/apt/sources.list.d/medibuntu.list /etc/apt/sources.list.d/ubuntu.list

Then update your repositories manually:
Code: Select all
apt update

If there are any errors remaining, please share those here and include also the output of:
Code: Select all
inxi -r


If no more errors, go ahead and try again to install p7zip-full.
