  • PPAs are 3rd party repositories, thus all security checks are on you. A quick look shows it's been *unsupported/unmaintained* since 2016; thus expecting it to support a modern release makes no sense, and anything in it is quite possibly a security risk given the lack of maintenance. Did you perform any checks? – guiverc Oct 25 '22 at 04:36
