This question already has an answer here:
My organisation has restricted installing software on all workstations to I.T. administrators only, so I am not able to check this myself.
All applications, including QGIS, are pushed through Software Center. Recently, they pushed QGIS 2.18.8 and it removed the last LTR version of QGIS and latest 2.18.6 version, from everyone's workstation. I wanted to confirm, would the new QGIS 2.18.8 installer have uninstalled both the previously installed QGIS versions, or could it be something set in the Software Center distribution/installation process?
We would like to be able to always have a LTR version of QGIS to fall back on, if the test version has issues, so I am trying to narrow down the problem.
This is different to the suggested duplicate topic in that there is a software deployment application being used and not manual installations of QGIS to individual users. I want to determine if the uninstalls are done by Software Center or by the QGIS installation package by default. We also don't want standalone versions, preferring to run multiple QGIS versions. One LTR and one Latest for testing new features.
