[CONFIGURATION] removal of unused Fonts?

[James the Third]

Is 24.04 sensitive to the script going around to remove unused Fonts? I used it in 23.10 with no issues.

You would have to post the exact contents of "the script going around" to get a reasonable answer.


PS: I would also generally strongly advise anyone not to use/run any "scripts from the internet" that don't come from trustworthy sources or whose contents have not been verified and understood by yourself or a person that has the ability to do this (that is one of the "general rules" regarding computer security - no matter which operating system you use).

Sorry. Mistake in title of first topic. It should be alien fonts not languages.

I would not use this script in Kubuntu 24.04 LTS as it will also remove something like fonts-noto-core… One might need this to display certain languages.

Additionally the script as posted will only keep English (British), English (US) and Italian language and help packages for LibreOffice and delete every other language support for LO!

It also tries to remove Firefox ESR (not available at all in Kubuntu 24.04 LTS) language files.
"echo "Firefox is bound to Libreoffice locales so apt will"[…]" - no it isn't in Kubuntu…


--> What exactly is your problem with fonts in Kubuntu 24.04 LTS?
Perhaps it would be better to find a solution for your problem instead of running this script…

Hello, I in agreement with the author that I have too many choices for my uses.
"but most of all, when you have to choose a font it's a lot easier/faster."
