[Bug 982082] Re: do-release-upgrade crashed with IOError in init_proxy(): [Errno 5] Input/output error

[Yvan Arnaud]

Hi,
this bug report is a bit old but as there is no answer yet, I'll describe my own experience with it.
I had a similar error after login on a fresh install of precise desktop.
Launching do-release-upgrade on command line reported an invalid proxy error.
I found out that I had an invalid proxy declaration in /etc/apt/apt.conf.
So, correcting the Acquire::http::proxy line with the valid proxy address was the solution for me.
Best regards
