On your failing machine, if you have clearos-centos-verified enabled you should also enable clearos-centos-updates-verified.

If you wanted to find the answer to what made it work, have a look you your yum log and check out the packages which were installed at the time with the yumdb command, or perhaps with "yum --enablerepo=* list --showduplicates then_your_package_list" which marks each package which you have installed.

I think it's one of those make me happy
but I can't figure which one..

yum clean all

yum-config-manager --enable clearos-updates

yum update

yum upgrade

yum --enablerepo=clearos-centos,centos-updates-unverified install fail2ban fail2ban-systemd

yum --enablerepo=clearos-centos,centos-updates-unverified install app-smtp-core

yum remove app-smtp-core

My bad, I'm unable to edit my last post

Hi Nick;
thanks for your help

I must did something important with yum but I can't figure what even by looking into my bash_history

I must did something important with yum because one of those worked

Hi;
I have the same error
this is the ERROR output of : yum --enablerepo=clearos-updates,clearos-centos install app-imap

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

those are my repos

Two things. Firstly you are running ClearOS 6.7 and not 7.x. Secondly, can you try running a modified form of Ben's command:

yum --enablerepo=clearos-centos-updates,clearos-centos install app-imap

I did all that and I still get the same problem.

Thanks for the reply.

So shall I go ahead and run

yum --enablerepo=clearos-updates,clearos-centos install app-imap

now?

To find out what is wrong, can you please post back the output of:

yum repolist

Once you do that, your solution to your problem is to run:

yum --enablerepo=clearos-updates,clearos-centos install app-imap
