See #65
Because of stucking lintian process, we can't enable lintian check on Ubuntu Focal (Arm64) and Groovy.
The reason why lintian process stalls is caused by IO::Async and that dependency was removed since lintian 2.92.0 [1], so we can remove this workaround from Ubuntu Hirsute (21.04) or later.
