I cannot edit my user crontab without being superuser.
I expected the following to work, but I get an error message:
$ crontab -e crontabs/gauthier/: fdopen: Permission denied
The following is working, but I don't think I should need sudo to edit my user-specific crontab:
$ sudo crontab -u gauthier -e
The permissions on my user crontab:
$ sudo ls -l /var/spool/cron/crontabs total 4 -rw------- 1 1001 crontab 1139 Sep 10 08:36 gauthier
I tried adding myself to the crontab group, to no av (I understand now that I shouldn't be in that group, it's only for SGID to work).
An answer to this question says to change the permissions, owner, and group of
/usr/bin/crontab, but that file does not seem involved here. And I don't see why these permissions would have changed from system defaults.
Where am I wrong? Is it normal that
crontab -e doesn't work? Even if I am in the
crontab group? What should I do instead? If I need to change the permissions and owner of
/usr/bin/crontab, why aren't they working in the default installation?
