CPANEL-40281 - Logwatch issue with cPanel on Ubuntu

izghitu
Hi, I just got Ubuntu 20 and set it up with cPanel. I found one issue with package dependencies when trying to install logwatch: root@server:~# apt install logwatch Reading package lists... Done Building dependency tree Reading state information... Done The following package was automatically installed and is no longer required: squashfs-tools Use 'apt autoremove' to remove it. The following additional packages will be installed: postfix Suggested packages: libsys-cpu-perl libsys-meminfo-perl procmail postfix-mysql postfix-pgsql postfix-ldap postfix-pcre postfix-lmdb postfix-sqlite sasl2-bin | dovecot-common resolvconf postfix-cdb mail-reader ufw postfix-doc The following NEW packages will be installed: logwatch postfix 0 upgraded, 2 newly installed, 0 to remove and 2 not upgraded. Need to get 366 kB/1,567 kB of archives. After this operation, 6,887 kB of additional disk space will be used. Do you want to continue? [Y/n] Get:1 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 logwatch all 7.5.2-1ubuntu1.3 [366 kB] Fetched 366 kB in 0s (1,073 kB/s) Preconfiguring packages ...

It looks like a bug. Any solution to this? Please help. Thanks

    Hey there! cPanel itself doesn't make or distribute logwatch, as that is handled by the operating system repositories. From the details I found, postfix is part of the logwatch software that Ubuntu provides, which would not be compatible with cPanel tools. This is not the case with CentOS systems, as the only dependencies there are the following: [root@host /]# yum install logwatch Last metadata expiration check: 3:45:41 ago on Mon 21 Mar 2022 03:25:46 PM UTC. Dependencies resolved. ======================================================================================================================================================================================================= Package Architecture Version Repository Size ======================================================================================================================================================================================================= Installing: logwatch noarch 7.4.3-11.el8 baseos 424 k Installing dependencies: perl-Date-Manip noarch 6.60-2.el8 baseos 1.1 M perl-Sys-CPU x86_64 0.61-14.el8 baseos 20 k perl-Sys-MemInfo x86_64 0.99-6.el8 baseos 27 k
    We can see the following on a Ubuntu system: # apt-cache depends logwatch logwatch Depends: perl |Depends: postfix Depends: citadel-server courier-mta esmtp-run exim4-daemon-light lsb-invalid-mta masqmail msmtp-mta nullmailer opensmtpd qmail-run sendmail-bin ssmtp dma exim4-daemon-heavy postfix Recommends: libdate-manip-perl Suggests: libsys-cpu-perl Suggests: libsys-meminfo-perl
    and we'll find postfix is in the "depends" list.

    Thanks for your reply. It is not necessarily postfix that is in the depends list. It is the "default-mta" or "mail-transport-agent" virtual packages that are in the depends list. The cpanel-exim package however does not make part of any of those virtual packages. So the question is how do I resolve this? How do I get logwatch installed and have dependencies satisfied? cPanel is supposed to work in such a manner that it does not break any of the official package dependencies. Is there perhaps any way to make the cpanel-exim package part of the "mail-transport-agent" virtual package?

    I've created case CPANEL-40281 so our team can check this out. I don't have a workaround available at this time, but I'll be sure to post once I hear something.

    Hi, Several months have passed since this was reported. Do you by any chance have any update on this? I have another Ubuntu server that has the exact same problem. Thanks in advance.

    I can see the task has been assigned to a specific development team, but I don't have any timeframe as to when it will be implemented. I can say that since logwatch isn't a required tool for cPanel, this is a bit lower priority case since it doesn't break anything within the cPanel software.
