Can you add to the automated build bot to add 16.04 and 18.04 the build single thread build for validating block explorer builds that are required for onion explorer to properly compile?
Open a ticket in the issue tracker. Maybe I will be able to do so if I find time, or someone else will.
I do not think anyone is using onion explorer on anything other than 16.04 right now but no way to confirm that. I think 420coupe was using 18.* but not sure
