It looks like it's available for chimaera (bullseye) and/or ceres (sid):

There are also rebuilds for beowulf here:

@Élisabeth . . . your tenacity is quite extraordinary!  Congratulations!

On the slim panel there is a note to  Press F1 to select sessions. Did that not work?

@Élisabeth . . . Have you looked at the install guide on the website?  There are images of the installation screens and comments too.  I am pretty sure that instructions are the same for chimaera.

sources.list info is detailed here.  Chimaera has not been released yet but you are welcome to test.  Otherwise use beowulf which is the current stable release.

Yeah, I mentioned Rufus early on.  Seems it got lost in the confusion,

@zapper . . . it would be nice if more of your responses actually contributed knowledge to Devuan . . .

The subject of this thread is misleading.  Chimaera has not been "officially" released yet.  Will be soon though . . .

Have a look at this post: https://dev1galaxy.org/viewtopic.php?pid=30971#p30971

Since I always do legacy boot not sure it's the issue you're experiencing but doesn't hurt to mention it.

Good intentions without action bears no fruit.  He who seeks, finds.  You are most welcome to offer solutions to posts on this forum or perhaps fix a bug.  Only you know your skillset and abilities and can choose to offer them to the community. 

Yes, there is a "we" at Devuan.  That is what's makes this distro unique and powerful.

I have not touched your email or forum accounts. Neither have I suggested or encouraged action to be taken by anyone else.

Just a hunch but it might be useful for you to understand how Devuan merges Debian repos with amprolla.
