Can you please try apt-get update & apt-get upgrade before running gm-installer? The problem may happen in older distributions because of this issue: https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/

Thank for reply.

I can't run "apt-get upgrade" because I have other systems installed on the server that would stop working.
Is there a possibility to install gm manually?

In this case you need to update at least the certificates. Try running update-ca-certificates. Please let me let me know if it helped.

the error still persists:
Err:10 https://repo.galera-manager.com/nexus/repository/galera-manager-release-1804 bionic Release
Certificate verification failed: The certificate is NOT trusted. The certificate chain uses expired certificate. Could not handshake: Error in the certificate verification. [IP: 134.209.245.63 443]

You can try bypassing the security mechanism:

touch /etc/apt/apt.conf.d/99verify-peer.conf
echo >> /etc/apt/apt.conf.d/99verify-peer.conf "Acquire { https::Verify-Peer false }"

And retry the installation. Note, this will effectively turn off https peer verification, which might make apt vulnerable for the MitM attacks.

Thank denisgcm for your help.
I decided install GM on Ubuntu 20 and there I have had no problems.
