I run Manjaro at home but my work PC they want to standardize on Ubuntu. 20.04 uses Qt 5.12.8 and the most recent commits use new functions available only in 5.15.
Recommendation: Simply create a tag or a branch off of commit 861a323229d34aa42c837bacb15a9d9f2cb9fa4f which works fine in 20.04 and add instructions in the readme to use that tag for Ubuntu.
