I just upgraded a machine to Ubuntu 25.10 and started seeing the following error messages from sudo (which is now infamously using sudo-rs implemented in rust)<\/p>\n\n\n\n

<\/pre>\n\n\n\nThese come from an older version of jellyfin, which installed that file. Current jellyfin does not install that at all (it was removed in 2023<\/a>). When I went to remove the offending lines in the file with visudo I was slightly worried due to the warning that I’d remove my ability to sudo visudo anything:<\/p>\n\n\n\n
$ sudo visudo \/etc\/sudoers.d\/jellyfin-sudoers
[...removes lines with requiretty on them and save...]
It looks like you have removed your ability to run 'sudo visudo' again.
What now? e(x)it without saving \/ (e)dit again \/ lock me out and (S)ave: S<\/pre>\n\n\n\nI ended up hitting save, confident that it was just sudo-rs being overzealous with its warnings. Sure enough, everything worked fine. Good luck!<\/p>\n","protected":false},"excerpt":{"rendered":"
