My user is a member of groups, one of which has a hyphen in it. /bin/id: uid=1001(viking) gid=1001(viking) groups=1001(viking),27(sudo),29(audio),44(video),119(pulse),120(pulse-access),1000(zoombuggy) Inside the debug buffer for tramp: ... groups-integer: (1001 27 29 44 119) groups-string: (viking sudo audio video pulse) ...
Local system is 64-bit Fedora 29, with emacs-29 (git revision: aa253c533d23d0fda1ecc512d94dea24501803ed). tramp version: 2.6.2.29.2 Remote system is 64-bit Ubuntu 22.04.
