visudo won’t actually stop working if you remove requiretty lines on Ubuntu 25.10

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)

$ sudo ls

These come from an older version of jellyfin, which installed that file. Current jellyfin does not install that at all (it was removed in 2023). 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:

$ 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

I ended up hitting save, confident that it was just sudo-rs being overzealous with its warnings. Sure enough, everything worked fine. Good luck!
