[Ophir LOJKINE (pere-jobs)]

I am affected by this bug too. How can it be marked as "medium", when it freezes the whole install process ?

[Matthias Metzger (macellarius)]

Have you tried to run do-release-upgrade in terminal?
The error message shows up anyway, but - in my case - the installation process continued without failing.

[Hannu Tikka (hannu-tikka)]

One more affected. Ubuntustdio upgrdes ok, but ubuntu server 16.04 on commandline upgrade stops to this bug.

[disasterpiece (vmf11)]

Same issue on 16.04.

Hello,

Same here, with do-release-upgrade and graphic interface.
Impossible to upgrade from 16.04 to 16.10.
The process goes on some minutes after le crash message but never goes to the end.

Both on virtual installation (VirtualBox) and hard plateform. (AMD64)

Easy to reproduce on VM if needed for debug.

Regards

[ROUCHY JMarc (jm-rouchy)]

Hello,

disasterpiece (vmf11)'s patch CORRECTS the bug.

Upgrade to 16.10 teminated !

Thank's.

[Juancho (juan-baptiste-0)]

I confirm it too, trying to update from kubuntu 16.04 to 16.10 I get that error at different points in installation, now I have a broken install because of this.

[Christophe Romain (cromain)]

I faced this issue as well.
it was solved with python3-distupgrade 16.04.19
and reapeared with python3-distupgrade 16.04.20

temporary solution "that works for me" is to force installation of python3-distupgrade 16.04.19
