#208912 — nother problem I can't access my crontab, no perms

Gut an ls -lR of /var/spool shows they are an exact copy of the wheezy 
files. With mine own by me.

What did I screw up now. I had noticed my kmail spam folder was filling 
up because my cron scripts aren't running as scheduled.  Otherwise I 
haven't touched it since installing stretch.

Any clues? Making me a member of the group shown made no diff, and it 
worked a treat under wheezy.
 
Cheers, Gene Heskett

Good Day Gene,

On coyote, /var/spool/cron contained:
> drwx-wx--T  2 root   systemd-timesync 4096 Mar 31 09:15 crontabs
         ^^^
You can't go through this "crontab" directory if you are not
root, or a member of the group systemd-timesync.  That includes
that you can't read any file below, even if it is attributed to
you.

I would tend to believe that execution of "crontab" related
commands will benefit from the proper UIDs when operating.  On
my machine, at the same working directory, I have:

	$ sudo ls -lR
	.:
	total 0
	drwx-wx--T 2 root crontab 21 Feb 28 22:49 crontabs
	
	./crontabs:
	total 4
	-rw------- 1 user crontab 381 Feb 28 22:49 user

It would seem that your restore attempt conserved UIDs, but
crontab's former UID has become systemd-timesyncd one.  Perhaps
a well placed `chgrp -R crontab crontabs/` will do?

Kind Regards,

Absolutely spot on,  Étienne Mollier, thank you very much.  Now cron has 
about 2 weeks work to catch up on. :)

Whoopsie, for the sake of precision, I mostly meant GID (Group
Identifier) instead of UID (User Identifier).

Glad to read that  :)
