Redmine

Hi there,
We are running a Redmine issue tracker internally in our organization, so it is not reachable outside our intranet.

It's Redmine 3.4.4 installed via apt on Ubuntu 18.04.

Every once in a few months, there is a Ruby error when we try to access the tracker. It has to do with different gems every time - the last one ad to do with mysql2 (so I had to install libmysqlclient-dev), before that it had to do with guard-rspec, before that I had to install an older version of some gem that had autoupdated (I think nokogiri).

Most of the time running `bundle update` and `bundle install ...` is enough, but there are too many times it isn't.

I have very little knowledge in Ruby/Ruby on Rails, and I am one of the few people who have access to the server. For this reason I really want to disable autoupdate of Redmine, and especially of all the gems, as things tend to go wrong and then make the tracker inaccessible.

So far I've set APT::Periodic::Update-Package-Lists "0"; and APT::Periodic::Unattended-Upgrade "0"; in /etc/apt/apt.conf.d/20auto-upgrades

Any other ideas?

Thanks!
