From the log:
update-alternatives: errore: l'alternativa pg_basebackup.1.gz non può essere slave di psql.1.gz: è slave di postmaster.1.gz

my italian is bad, but it seems to be that the file is owned by multiple packages.
I tried to upgrade in a container and it worked.

Could you run:
dpkg -S pg_basebackup.1.gz psql.1.gz postmaster.1.gz

Is any of the packages that lists you form a ppa or any other 3rd party source that would explain why it doesn't work for you?

Also related you could report:
update-alternatives --get-selections

In there look for the names above.

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

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or 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, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.
