Not really, GCC 12 is just the default on Bullseye, GCC 10 seems to be 
available there too. So I should attempt to build and link with GCC 10?

I don't really build .deb packages, Golang compiler produces one static 
binary, so that would be redundant.

We already have a solution to build this in Docker, though the target 
test VPS is tight on resources and I wouldn't really like to mess with 
Docker there.

My scenario is developing the project on one VPS, building it there and 
sending test builds (just copying one binary file, pretty easy) to 
another VPS where they are run. Previously they had the same Debian 
version, so this was a non-issue; recently I upgraded the first one to 
Bullseye, but the target VPS has some legacy and 3rd party software 
running, so an upgrade would be complicated and I postponed it for now. 
I could actually run the builds on the development VPS as well, migrate 
project data there and bind a remote port via SSH, but this would make 
it more prone to network interruptions.
