[Bug 1763747] Re: Cannot upgrade from 16.04.4 to 18.10

[Jean-Baptiste Lallement]

Thanks for your report.

You have package from non-official repositories installed which are
blocking the upgrade.

In particular python3.6:

libpython3.6 3.6.3-1+xenial2 LP-PPA-thomas-schiex-blender
libpython3.6-minimal 3.6.3-1+xenial2 LP-PPA-thomas-schiex-blender
libpython3.6-stdlib 3.6.3-1+xenial2 LP-PPA-thomas-schiex-blender

which is not in Xenial.

Please uninstall these packages before upgrading again or revert to a
version from the official Ubuntu repository.

I'm closing this report. Don't hesitate to file any bug you may find.
