QGis

Is it save to downgrade the python-sip package?

python-sip=4.17+dfsg-1build1

Installed is:

Code:

4.19.2+dfsg-1+16.04+xenial+build5 500
       500 http://ds9-maui.s3-website.eu-central-1.amazonaws.com/maui-xenial-backports-neon xenial/main amd64 Packages
       100 /var/lib/dpkg/status

4.17. seems to be required for installation of QGis.

That will potentially break other stuff. So not it is not safe.
QGIS needs to be recompiled against this newer version.
