[Erich Eickmeyer (eeickmeyer)]

This isn't a bug in Ardour, but a known bug with the Calf plugins. This should be fixed with the release of 0.90.1, which is in the queue.

[Erich Eickmeyer (eeickmeyer)]

I hesitate to mark this as a dupicate, but here's the related bug report: https://bugs.launchpad.net/ubuntu/+source/calf/+bug/1769785

One workaround is to remove the calf-ladspa package, which should be done anyhow as it's depricated.

[Launchpad Janitor (janitor)]

This bug was fixed in the package calf - 0.90.1-1
