package openssh-server 1:5.3p1-3ubuntu7 failed to install/upgrade: el subproceso post-installation script devolvió el código de salida de error 2

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

This looks like a local configuration problem, rather than a bug in Ubuntu, so I'm marking this bug as Invalid.

Specifically, you seem to be running some packages from 8.04, and some from 10.04. Is this part of an aborted or incomplete upgrade?

You can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

If you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, and then change the bug status back to New.
