This is the screenshot from my jetbrains toolbox (version 220.127.116.1144, Linux Mint 20.3 (Linux 5.4.0-166-generic), x64).
At the initial set up, I may have set up pycharm standalone, then I have likely set up jetbrains toolbox, and installed some other tools with it. Even I cannot retrace the steps now, and not sure if the toolbox automatically incorporates the standalone installations that existed before it (as in I can see the standalone versions, uninstall or update them etc. via the toolbox).
The point being, the toolbox seems to show some outdated versions installed, along with newer versions. When I try to install the outdated versions by clicking uninstall in the toolbox, I get an error message
The specified directory is not writable
The questions are
Are the outdated versions eating my disk space?
Are the versions totally independent, as in the plugins installed, the editor settings etc. or are those loaded from common configurations?
How to remove the outdated versions without breaking the newer versions, while retaining as much of the settings and plugins as possible?
