Hello, After upgrading from GNU Emacs 28.2 to GNU Emacs 29.1 (Debian packages) I noticed a regression when I try to open a file on a remote host where my user has write access through its group : it's opened in read-only mode.
The command I used : emacs -nw -Q --eval "(setq tramp-verbose 7)" /ssh:dockdev.pilotsystems.net:/home/crfpa/foo.txt The permission of the file : -rw-rw-r-- 1 crfpa crfpa 19 Oct 27 10:47 /home/crfpa/foo.txt The result of id for my user on the remote host : uid=10002(kilobug) gid=10002(kilobug) groups=10002(kilobug),4(adm),33(www-data),998(docker),1000(crfpa),1002(wpk),1003(probarreau),1004(ae) There is no SELinux or ACL or anything of that kind. After looking at the *debug tramp/ssh dockdev.pilotsystems.net* buffer that seems to be the issue : 10:28:20.336793 tramp-send-command (6) # /bin/id 10:28:20.342457 tramp-wait-for-regexp (6) # uid=10002(kilobug) gid=10002(kilobug) groups=10002(kilobug),4(adm),33(www-data),998(docker),1000(crfpa),1002(wpk),1003(probarreau),1004(ae) ///ac59c02ea7871e6263e190f14ec29c44#$ 10:28:20.342588 tramp-get-connection-property (7) # process-buffer nil; cache used: t 10:28:20.342699 tramp-set-connection-property (7) # uid-integer 10002 10:28:20.342764 tramp-set-connection-property (7) # uid-string kilobug 10:28:20.342815 tramp-set-connection-property (7) # gid-integer 10002 10:28:20.342884 tramp-set-connection-property (7) # gid-string kilobug 10:28:20.342934 tramp-set-connection-property (7) # groups-integer (10002 4) 10:28:20.342991 tramp-set-connection-property (7) # groups-string (kilobug adm) The parsing of the groups I belong to stops when it reaches "www-data" which has "-" in its name. If I remove myself from the group, then it works (file is properly opened in read-write mode). I got the issue confirmed by another user of #emacs IRC channel.
