Upon further review, I've found a bug report for this same issue on Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=968964
The issue stems from this commit: https://salsa.debian.org/go- team/packages/golang-github-xenolf- lego/-/commit/f2a108f0528a5e0ec5038d43d7a85ec301cb1f96#8756c63497c8dc39f7773438edf53b220c773f67_3_12 The change uses the Debian rules file to selectively remove support for a significant number of DNS providers at compile time, while leaving the `lego dnshelp` output untouched, and telling users that the providers are still supported. This change was also not noted in the commit message. The fact that this change does not seem to fix any other issues, does not add any features, removes documented features, and was not noted in the commit messages, seems to suggest that it might not have been intentionally committed. With this in mind, would it be acceptable for us to remove these changes from the Ubuntu package and add back the documented functionality from the upstream project? ** Bug watch added: Debian Bug tracker #968964 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=968964 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971029 Title: Cloudflare not recognized for DNS validation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/golang-github-xenolf-lego/+bug/1971029/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
