Ubuntu Gitlab package broken?

Hi,

I’m trying to update Gitlab on Ubuntu server 18.04 but it seems there’s something wrong with the package:

Any fix?

The GPG keys rotated recently, which would explain why your update is failing.
Please have a look at the The GPG key used to sign GitLab package repositories’ metadata is changing blog post which gives a full description, plus instructions on how to get a new key.
Once you have the new key the update should be successful.

Ah ok that makes sense. Thanks for the info and the blog post! I will get a new key
