The Devuan website looks hacked. Given the timing, it's probable that it is an April's Fools Joke, though it's not clear if it's the Devuan devs' April's Fools joke or the hackers' April's Fools Joke. In any case, it's probably better for any Devuan users to avoid updating their packages and keep an eye out for signs of compromise.
If it is a joke by the devs, then they are taking it pretty far since official channels of communication say that the hack is real (but package are not compromised): https://lists.dyne.org/lurker/message/20190331.191104.169aaf9a.en.html
In any case, it's a warning about taking Devuan too seriously; either they don't know how to secure their servers, or they don't know what it means to take a joke too far.

It's nice that there is still a sense of scruffy hacker humour around. There are large parts of the free software community which has become boring, politically correct and corporate like as if we're selling a product. I like the stupid jokes and the sarcasm. I want communities that are fun to be in and not one where I feel like I'm an unpaid slave who works on software. Having fun on IRC and mailing lists is important. If I can't have fun while I program, I want a paycheck.
This joke was great. I fear that people who took offense to the joke, have serious security issues, because it appears like they base their entire sense of security on trust. Security is a method and not one that is based on faith and don't deal with failure.
