I have not used my Ubuntu 12.4 (64 bit) netbook for about a year, and yesterday I tried to install one year worth of updates at once. The update did not go smoothly: I had to restart the netbook a few times because the Update Manager behaved strange.
Now I have about a half of the new packages installed, and I cannot go any further because I have two broken packages:
I did not have any third-party repositories enabled, but the
Unsupported updates (precise-backports) option had been enabled.
What I have tried
When I use
sudo apt-get install -f I get an error message:
dpkg: error processing libjpeg-turbo8 (--configure): libjpeg-turbo8:amd64 1.1.90+svn733-0ubuntu4.1 cannot be configured because libjpeg-turbo8:i386 is in a different version (1.1.90+svn733-0ubuntu4.3) dpkg: error processing libjpeg-turbo8:i386 (--configure): libjpeg-turbo8:i386 1.1.90+svn733-0ubuntu4.3 cannot be configured because libjpeg-turbo8:amd64 is in a different version (1.1.90+svn733-0ubuntu4.1)
I looks like
libjpeg-turbo8:i386 are in a deadlock: neither can be installed/configured because the other has a different version.
I cannot remove the broken packages, because too many other programs depend on them and would be removed too. The
Mark for upgrade and
Mark for reinstallation options in Synaptic do not work either. Neither does the
Force version... menu.
How can I solve the problem?
