[DRE-maint] Bug#837638: ruby-devise-async: Incompatible with ruby-devise 4

[Jeremy Bicha]

Package: ruby-devise-async
Version: 0.9.0-1
Severity: serious

Ever since ruby-devise 4.1.1-2 was uploaded to Debian unstable,
ruby-devise-async has been failing its autopkgtests.

https://ci.debian.net/packages/r/ruby-devise-async/unstable/amd64/

I looked upstream and it's apparently a known issue:

Thanks,
