For `dist: bionic`, Xenial VM is used instead with `language: perl`

Trying to using Bionic for perl project, however Xenial binaries show up instead. Build headers show Bionic is specified but not used.

Build language: perl

This long-standing bug seems to have been fixed recently, but now it is showing other gaps in Perl coverage: Perl 5.28 not available on bionic

Thanks for the update. Agreeing / confirming this particular bug is fixed for me.

Also seeing the missing perl versions support, will report details in your thread.
