Title:
Logrotate failed to start in LUbuntu 20.04
Status in samba package in Ubuntu:
Confirmed
Bug description:
After fresh installation of LUbuntu 20.04, when I switched off
Plymouth, failure of logrotate appeared on the screen during boot.
(PIDs are replaced by ***)

I compared /etc/logrotate.d/samba with the information at
https://salsa.debian.org/samba-team/samba/commit/bed29aba47558252eacfe9453d23cc1ab29770aa
Two different lines have been found:
In /etc/logrotate.d/samba:
line 6: [ ! -x /usr/bin/smbcontrol ] || [ ! -f /run/samba/smbd.pid ]
|| /usr/bin/smbcontrol smbd reload-config
line 18: [ ! -x /usr/bin/smbcontrol ] || [ ! -f /run/samba/nmbd.pid ]
|| /usr/bin/smbcontrol nmbd reload-config
at https://...
line 6: [ ! -x /usr/bin/smbcontrol ] || [ ! -f /var/run/samba/nmbd.pid
] || /usr/bin/smbcontrol nmbd reload-config
line 18: [ ! -x /usr/bin/smbcontrol ] || [ ! -f
/var/run/samba/nmbd.pid ] || /usr/bin/smbcontrol nmbd reload-config
There is a same difference: in LUbuntu 20.04 .pid files are searched
in /run/samba/, but at https://... they are searched in
/var/run/samba/. After boot, both are present and have the same PIDs.
:~$ cat /var/run/samba/nmbd.pid
abcd
:~$ cat /run/samba/nmbd.pid
abcd
:~$ cat /var/run/samba/smbd.pid
efgh
:~$ cat /run/samba/smbd.pid
efgh
(digits are replaced by letters for security reasons)
Changing the folders according to https://... and reboot solve the
problem:
:~$ systemctl status logrotate
● logrotate.service - Rotate log files
Loaded: loaded (/lib/systemd/system/logrotate.service; static; vendor
preset: enabled)
Active: inactive (dead)
TriggeredBy: ● logrotate.timer
Docs: man:logrotate(8)
man:logrotate.conf(5)
After that, I tried to revert the changes and reboot. The bug cannot
be reproduced anymore.
Additional information:
:~$ lsb_release -rd
Description: Ubuntu 20.04 LTS
Release: 20.04
:~$ apt-cache policy logrotate
logrotate:
Installed: 3.14.0-4ubuntu3
Candidate: 3.14.0-4ubuntu3
Version Table:
*** 3.14.0-4ubuntu3 500
500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages
100 /var/lib/dpkg/status
Finally, the solution for me is:
sudo <installed text editor> /etc/logrotate.d/samba
Replace the following line (for me, line 6)
[ ! -x /usr/bin/smbcontrol ] || [ ! -f /run/samba/smbd.pid ] ||
/usr/bin/smbcontrol smbd reload-config
by
[ ! -x /usr/bin/smbcontrol ] || [ ! -f /var/run/samba/nmbd.pid ] ||
/usr/bin/smbcontrol nmbd reload-config
and the following line (for me, line 18)
[ ! -x /usr/bin/smbcontrol ] || [ ! -f /run/samba/nmbd.pid ] ||
/usr/bin/smbcontrol nmbd reload-config
by
[ ! -x /usr/bin/smbcontrol ] || [ ! -f /var/run/samba/nmbd.pid ] ||
/usr/bin/smbcontrol nmbd reload-config
Save and reboot.
But there are two question.
Is it necessary to check both .pid files (both are present after boot), if
yes, what operator should be used, || or && ?
Is it necessary to correct line 32: "elif [ -f /run/samba/samba.pid ];
then"? I did not correct it.
Because of a short time after installation, it is not tested, are the
log files rotated or not.
