## TL;DR
|
|
|
|
> Do **not** install custom alternatives for `python3` on SUSE systems.<br/>
|
|
> `/usr/bin/python3` does **not** have update alternatives there due to system tools dependencies and always points to
|
|
> specific tested versions. Creating custom `python3` alternatives pointing to different versions — i.e., `python3.11`
|
|
> — **will** break dependent system tools.
