QGIS fails after upgrade to 16.10 from 16.04

[Christopher Barrington-Leigh]

Trying to run qgis results in the following (QGIS closes immediately / fails to run).
I just upgraded from 16.04 to 16.10

$ qgis

I'm sorry to hear QGIS doesn't work on yakkety, unfortunately the qgis package is in universe which is entirely unsupported.

You can give the upstream QGIS packages a try which have more recent LTR versions available:

[Christopher Barrington-Leigh (cpbl)]

Thanks, but I don't know how. They don't seem to have a yakkety version. Trying to use the xenial version of the ltr or bleeding repository on yakkety leads to failure to install qgis.

[Christopher Barrington-Leigh (cpbl)]

Ah, in fact, a workaround for the original problem for me turns out to be do delete or rename my ~/.qgis2 folder.

[Johan Van de Wauw (johanvdw)]

I tested the universe package on a fresh yaketi install and it works fine for me. I think it is indeed a problem with your config.

[Christopher Barrington-Leigh (cpbl)]

Thanks. Yes, my config was fine before the upgrade. The bug is in the upgrading when users already have a configuration.

just to share some light...

the same error happens in debian recently after upgrading the qgis-2.99 to more recent dev version, so probably it propagates from debian...

"the same error happens in debian recently after upgrading the qgis-2.99 to more recent dev version, so probably it propagates from debian..."

QGIS 2.99 is not in Debian, nor Ubuntu. This is not the venue for issues with the upstream packages.

I also had this problem after upgrading my scipy to version 0.19.1, which was interfering with loading QGIS. The issue was solved after downgrading scipy to version 0.11:

pip install scipy==0.11
