[Qgis-user] QGIS uninstalled after GDAL PPA install

[Ben Hur Pintor]

Hi Lorenzo,

Ubuntu and QGIS user here as well. I use the ubuntugis-unstable for the
most recent libraries on Bionic (w/o needing to compile the libs myself).
I'm currently still on 3.10.2 since that's the most recent version in the
unstable PPA (w/ GDAL 3.0.2 and PROJ 6.2.1).

For Ubuntu, the ubuntugis-unstable PPA usually contains the most recent
library versions available. The main (universe) repos rarely update
themselves. Which is why GDAL 3.X and Proj 6.X is available via the
unstable PPA and not the main repo.

One thing you can do is compile the libraries yourself for Bionic.

Another is to wait for ubuntugis-unstable to update their packages.

Another is to wait for Focal (20.04) to be released. Based on the
development docs of focal, it'll be released with GDAL 3.0.4 (
https://launchpad.net/ubuntu/focal/+source/gdal) and  PROJ 6.3.1 (
https://launchpad.net/ubuntu/focal/+source/proj) which looks great for
running the recent LRs and LTRs of QGIS.

You can see the note on the QGIS documentation here (
https://qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu)


All the best,
Ben Hur
