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.

I have to tell you that yes this was an april fools joke. Obvious to those in the Devuan community because of the use of gopher, which some people in the community are fond of in a kind of nostalgic way. Remember, take NOTHING seriously on April 1st. Just mark it on your calender as 'ignore the news day'.
And yes Debian were once compromised, four of their servers were totally owned for real. Which should be a valuable lesson to all, that nothing is really secure no matter how obscure it is. At the time you'd call GNU/Linux in general more obscure and it had much less focus by people trying to do nasty things, the other lesson was that upstream kernel developers shouldn't have ignored the critical security issue that had been known about for a long time.
The good news is that whilst not the best and having it's problems, GNU/Linux is not really bad like Windows is.
