Upgrading from 15.0.5 to 15.4.6

Hi,

I am doing upgrades on my gitlab server, but I’m having problems when trying to upgrade to 15.0.5 to 15.4.6. I’m using a red hat 8 Linux box, I type the command dnf install (package name) in which case is the version 15.4.6 but error come about and now I can’t access my gitlab via the browser.

The error says gitlab she’ll has been deprecated since 14.8 and was removed in 15.0. SelfsignedCert has been deprecated and will be removed.Install self-signed certificate into ‘/etc/gitlab/trusted-certs’ instead.

Any help please
