I waited for quite a bit before taking the plunge, but the server is finally updated to Ubuntu 20.
As I’d foreseen some things broke, but nothing major that wasn’t easily fixed.
I don’t have much time nowadays to work on hobby projects like this, so it was a relieve things went relatively smooth.
Besides the update, I started using report-uri.com on parts of this domain. Mainly to tackle some long-standing issues with a stricter CSP header.
It works quite easy, and a handy tool to debug and find the CSP problems on your sites.
