Redmine Server Install: Package "redmine" broken

Hello,
I am trying to install redmine on my server (Ubuntu 21.10 x64)
When I try to use 'apt-get install redmine redmine-mysql' I get an error message that there is no package installation candidate.

I have downloaded the most recent stable release to my server but don't feel confident in setting it up from source.

Can anyone fix the package issue so that I can install it through the package manager?
