Unfortunately, the version in Focal is frozen, and has been since February of 2020. No newer version of any package, unless it's either a security fix or extremely minor bugfix, can be backported. That said, I can make sure the newer version ends up in Ubuntu going forward.
Please consider using newer tools, such as ubuntu studio controls, or studio controls from the Ubuntu Studio Backports PPA. ** Changed in: qjackctl (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1907005 Title: package is 3 years behind upstream and Debian To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qjackctl/+bug/1907005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
