I installed 5.18 from backports, but unfortunately, they still didn't work.

(However, on a whim, I tried them under an Ubuntu live session, & they worked - so hopefully, all I've got to do is find the right modules & put them into my Devuan installations. )

@Ogis1975:

When Devuan has as many maintainers as Debian has, I would likely expect the same, but until then......

(These things happen.....some other software maintainers have been known to forget to renew keys too.)

EDIT: So glad this problem was sorted out so quickly, many thanks.

Just ordered some pre used computer books....having a reminisce of command line days.

Evil Geniuses in a Nutshell

It was introduced because a lot of admins had problems configuring sudo properly, & it has a lot less options, which makes it easier.

They introduced doas just after I finally got around to buying Sudo Mastery, just my luck.

Once released, I think you should be able to upgrade your system to it, & get all the new bits.

I was on 78.12, so I upgraded, & now its 91.11.0esr, hope that helps.

Just one small problem I've encountered, so far, it doesn't seem to like Radeon graphics (running on a HP thin client - it only gives 800x600) - I shall have to see what Devuan Live loads & add them in...

(This was the Fluxbox version, just in case it matters.)

EDIT: Seems to be the VGA graphics card controlling the D-sub socket. If I attach a DP to VGA converter cable I get SXGA - but if I use Devuan Live, I get a whole load of options - so these thin clients have gone back to that.

(EDIT2: My other thin client is also using the Devuan Live, & that too gives me loads of options, using a DP to VGA, or DP to HDMI cable.)

EDIT3: My little laptop is now using the Fluxbox version, I prefer it to JWM.

If I want something other than Firefox ESR, i download it from Mozilla website to a directory in my /home directory, & then run it from there, works without interferring with the main one.

My main keyboard is a CiT KB-738, its small overall size is what drew me to it, I hate those massive keyboards with keypads & multi media keys, this is just a keyboard.

When I'm setting up my RPi, I often use a wireless mini keyboard with touch pad.

Maybe one of the above may appeal to you.

EDIT: Almost forgot, I use xvkbd on my thin client computer, I don't type much generally, & this suffices for online web browser, music, videos, & time wasting games.

I'm running Devuan on my RPi4B/4G & my RPi400, but I'm a Fluxbox fan myself - they have plenty of power for whatever you want to do.

I was also running it on my RPi3B+ (1G ram) & RPi3A+ (512M ram), prior to giving them to our local Code Club, (as I was no longer using them).

Perfectly possible, I often do it with various distros.

Just plug in the pendrive, & use it as the disk to install to, only proviso, just make sure it is the one that has grub installed to it.
