Description of problem: Latest version of dehydrated has a dependency issue on a Red Hat Enterprise Linux 8.9 or Rocky 8.9 system. Version-Release number of selected component (if applicable): 0.7.1-1.el8.noarch How reproducible: Install latest dehydrated package on fresh RHEL8 or Rocky 8 system. Steps to Reproduce: 1. Install and register RHEL8 or install Rocky 8 2. Enable EPEL8 (install epel-release) 3. Install latest dehydrated package Actual results: dnf install dehydrated results in: Error: Problem: conflicting requests - nothing provides /usr/bin/mailx needed by dehydrated-0.7.1-1.el8.noarch from Expected results: Installs correctly when mailx is available. Additional info: mailx was already installed on this particular system, and present in the mentioned location, but according to the RPM itself it's installed in /bin/mailx. On EL8, the /bin directory is a symlink to /usr/bin, so eventually /usr/bin/mailx is available, but DNF doesn't know about that. Version 0.7.0-3 works correctly. I have the feeling this issue was introduced by https://bugzilla.redhat.com/show_bug.cgi?id=2050852 in attempt to fix a dependency issue on EL9.
Honestly, I'm in doubt that you are installing dehydrated really from EPEL 8, because: # dnf install dehydrated Last metadata expiration check: 0:01:36 ago on Thu May 9 17:46:41 2024.

You are absolutely right, my apologies (and also my appologies for the late response, I was on vacation in between). All our systems are behind Red Hat Satellite / Foreman, with filters on EPEL, so the s-nail package was unavailable. However, I expected the default mailx-package to be sufficient as a dependency, but instead, way worse thing happen. Let me explain. Situation: - Brand new Rocky 8.10 minimal system, direct internet connection (no Satellite/Foreman), only updated and rebooted once. - Installed epel-release. Now I install mailx, as we have that on our production servers: [root@rocky8 ~]# yum install mailx Last metadata expiration check: 0:00:14 ago on Mon 03 Jun 2024 11:15:58 AM CEST.

So far so good. Let me get the md5sum of the executable: [root@rocky8 ~]# md5sum /usr/bin/mailx bc25bfe29293d27c4eb0e38346fc3791 /usr/bin/mailx Now I install dehydrated: [root@rocky8 ~]# yum install dehydrated Last metadata expiration check: 0:00:38 ago on Mon 03 Jun 2024 11:15:58 AM CEST.

Seems good as well, however: [root@rocky8 ~]# md5sum /usr/bin/mailx 2a7e90d21ffdd5f7e776012743621ddb /usr/bin/mailx The MD5sum of mailx has changed! This seems to be caused by: [root@rocky8 ~]# rpm -ql mailx | grep 'bin/mailx' /bin/mailx [root@rocky8 ~]# rpm -ql s-nail | grep 'bin/mailx' /usr/bin/mailx /usr/bin/mailx.s-nail [root@rocky8 ~]# ls -als /bin 0 lrwxrwxrwx. 1 root root 7 Oct 11 2021 /bin -> usr/bin DNF/RPM has no knowledge of the symlink from /bin to /usr/bin, and therefore it treats them as different files, causing s-nail to just bluntly overwrite mailx, while the mailx package is still installed. This obviously is not an issue in the dehydrated package, but it points out why I want filters on EPEL, as not all packages play nicely with each other. I´d really like to see the mailx package from the base repository to be the dependency for dehydrated in EPEL8 again, and only use s-nail in EPEL9.
