Deleting the cache and the manual update fixed it. Obviously somehow the cache got corrupted.

It could be that, as it's a VM that is saved and backed up nightly, a hiccup caused the problem - although the 'save state, then resume' (VirtualBox) is supposed to resume transparently - although I had a couple of occasions when it shut down rather than 'saved'. Depends, I guess, if the VM was doing the update when it was shut down (by whatever means).

Mmm...
Odd.
Perhaps I'll try a manual update ..

yum list python-2.7.5* --show-duplicates -d1

There (shouldn't be!) anything locking it as this particular server is a dedicated mail server .. and, of course, the error is 'not found'. Very strange

It's the community edition, with a paid Kopano licence.

Updates have been working quite happily UNTIL this latest Kopano update, so it's a dependency issue.

 You could try using --skip-broken to work around the problem

 You could try running: rpm -Va --nofiles --nodigest

[r

I am not seeing any repo issues here. Also do you have a paid or Community version of ClearOS.
