[SOLVED] Duplicate log entry for /var/log/wtm - logrotate.conf error

Hello:

There is a bug in the logrotate.conf configuration.
See here: https://bugs.launchpad.net/ubuntu/+sour … ug/1915759

ralph.ronnquist pointed it out to me here: https://dev1galaxy.org/viewtopic.php?pid=28663#p28663 while helping me with an anacron problem caused (probably) live-config.
The error shows up when logrotate is run in /etc/cron.whatever and then you get notifocaton from the system:

From root@devuan Thu Apr 01 11:31:07 2021
Envelope-to: root@devuan
Delivery-date: Thu, 01 Apr 2021 11:31:07 -0300
From: Anacron <root@devuan>
To: root@devuan
Subject: Anacron job 'cron.daily' on devuan
Content-Type: text/plain; charset=US-ASCII
Date: Thu, 01 Apr 2021 11:31:07 -0300

/etc/cron.daily/logrotate:
error: /etc/logrotate.conf:18 duplicate log entry for /var/log/wtmp
error: /etc/logrotate.conf:25 duplicate log entry for /var/log/btmp
run-parts: /etc/cron.daily/logrotate exited with return code 1

The problem is that the fix posted is an Ubuntu fix.
ie: probably will not run properly in Devuan without adjusting it

Anyone know how to edit it so it will run?

Thanks in advance.

Cheers,

A.

Have you actually tried applying the fix? It looks fairly generic.

(FWIW I don't have any wtmp lines in /etc/logrotate.conf in my bullseye system.)

Re: [SOLVED] Duplicate log entry for /var/log/wtm - logrotate.conf error

Hello:

Have you actually tried ...

Yes.
At least in my system it is not a drop-in replacement.

There is at least one thing I noticed.
And the fixed logrotate.conf has this:

# use the syslog group by default, since this is the owning group
# of /var/log/syslog.
su root syslog

In Devuan Beowulf there is not syslog group (at least I can't find it).

groucho@devuan:~$ grep syslog /etc/group
groucho@devuan:~$ 

Also, syslog is owned by root but belongs to the adm group:

groucho@devuan:~$ ls -l /var/log/syslog
-rw-r----- 1 root adm 4816 Apr  1 13:30 /var/log/syslog
groucho@devuan:~$ 

That's why I think someone esle with proper skills has to have a look.

... don't have any wtmp lines in /etc/logrotate.conf in my bullseye ...

My Devuan Beowulf has it:

roucho@devuan:~$ cat /etc/logrotate.conf
# see "man logrotate" for details
# rotate log files weekly
weekly

# keep 4 weeks worth of backlogs
rotate 4

# create new (empty) log files after rotating old ones
create

# uncomment this if you want your log files compressed
compress

# packages drop log rotation information into this directory
include /etc/logrotate.d

# no packages own wtmp, or btmp -- we'll rotate them here
/var/log/wtmp {   <----- | x |
    missingok
    monthly
    create 0664 root utmp
    rotate 1
}

/var/log/btmp {   <----- | x |
    missingok
    monthly
    create 0660 root utmp
    rotate 1
}

# system-specific logs may be configured here
groucho@devuan:~$ 

So apparently that is why we get the mail I posted.

What does your logrotate.conf look like?

Thanks for your input.

Best,

A.

Why not? What happens when you comment-out the wtmp & btmp stanzas?

What does your logrotate.conf look like?

Hello:

Don't know.
I did not edit anything, I just renamed the original as logrotate.old and copied the new one in.

https://salsa.debian.org/debian/logrota … otate.conf

My Devuan Beowulf has logrotate 3.14.0:

groucho@devuan:~$ sudo logrotate --version
logrotate 3.14.0

    Default mail command:       /usr/bin/mail
    Default compress command:   /bin/gzip
    Default uncompress command: /bin/gunzip
    Default compress extension: .gz
    Default state file path:    /var/lib/logrotate/status
    ACL support:                yes
    SELinux support:            yes
groucho@devuan:~$ 

But for some strange reason, the logrotate.conf file I have is the logrotate.conf file packaged with logrotate 3.13.0, without this line:

--- snip ---
# use date as a suffix of the rotated file    <---- | x |
dateext
--- snip ---

The rest is the same.

See: https://github.com/logrotate/logrotate/ … 3.0.tar.gz

I'll get the .*conf file from logrotate 3.14.0 and use that.
Will report back once done.

Edit:
Works, no errors.
But my logrotate.conf file was the wrong version.

Thanks for your input.
 
Best,

A.
