Yes, we just started the perl 5.26 transition.

https://people.canonical.com/~ubuntu-archive/transitions/html/perl5.26.html

Please don't run proposed during the development cycle unless you want to experience these kinds of issues.

I'm closing this bug since this issue is likely already being taken care of without this bug. If this issue still happens after perl 5.26 migrates out of proposed, feel free to reopen this bug.
