Arch Linux

from what i have read, the 'rank-amateur-cowsay' repo was added
to github by the original author, after taking-down the
website and making it known publicly, that the project was being
abandoned, and that bug reports will not be accepted

some time later, the 'cowsay-org' repo was established to
continue maintenance as a community project

https://github.com/cowsay-org/cowsay/

regardlss of the web url, you may consider using the 'cowsay-org'
repo as the source upstream now - there is a debian ticket,
considering the same, on which the new maintainer has stated the
intention to maintain it upstream, into the future

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=988667

Fedora and Gentoo are using the one suggested in the above comment.

OpenBSD is using https://metacpan.org/dist/Acme-Cow

Debian/Ubuntu, Alpine, and FreeBSD are still using the old archived one.

I contacted the cowsay-org upstream about a couple bugs in the latest release. If he gets them sorted and tags a new version, I'll switch our package to that fork (assuming anthraxx doesn't have any objection).

cowsay-org upstream went silent, so we'll consider switching to that fork whenever it's ready.

Closing this task for now and using the archive.org link for the current package.
