I have TeXLive 2022 installed on my system - it's my Linux distribution's default. If I run tlmgr --gui, and try to load the default repository (URL: https://mirror.ctan.org/systems/texline/tlnet) - I get an error, because at that URL the version is now 2023.
How can I get a URL appropriate for my version? (Or - am I wrong to try?)
Note: I would rather not upgrade.
