从Ubuntu 12.04升级到14.04时Python中断

Question

Hi I am trying to update Ubuntu 12.04 LTS to 14.04 LTS via "do-release-upgrade" but still got:

Cant get any information on web to fix this. I already updated python 2.7.3 to python 2.7.11, tried linking to python3. Still the same issue...

Any ideas?

Answer 1

I already "fixed" this issue by killing sshd directly, hardly reinstalled python2.7.12 by compiling from source.

Got some python errors on end of upgrade... After upgrading everything seems to be fine.
