Looks like that was a typical temporary hickup of the testing repo and its mirrors.

Glad that its solved now.

Maybe the mirror isn't up to date? Perhaps you try deb.devuan.org/merged instead?

Well, the netinstall is meant for computers which have a working (wired) network connection to download everything that is not on this small media. So if the wifi requires drivers most likely they are not included. You either need to use the CD or DVD version, or identify the chip used.

Please run and poste output here. inxi could be an alternative.

# lspci | grep network
# lsusb | grep network
# inxi -Fz

Try the netinstall ...

Oh, copy & paste problem, sorry for that. When having a very close look to my command I saw that for some reason the first "–" before the "u" is a long hyphen instead of a normal dash "-". Some damn auto-correction mechanism ...

Just replace the long hyphen by a dash. Then it should work.

Use the Download link on the top of this page. Select devuan_daedalus. Then select installer_iso.

There you got the choice. The 4G one is the Desktop DVD.

Have a look at geany

Your problem is that Gnome like other DEs does not supply a mixer on its own.

pavucontrol, alsamixer-gui are valid options to solve the issue.

I own a small wireless mouse by Trust, item no.  20322-09. It runs on 2 AAA cells. The Bluetooth? dongle is stored inside the mouse when its not used. This mouse has an on/off switch.
I am mainly using it on my laptop. It worked out of the box with Chimaera and Daedalus, in both cases LightDM/Cinnamon as DE. No special action required. I can start the laptop, and plug in the mouse when I am logged in. It works.

VBox works fine for me, currently I am on Daedalus/kernel 6.5 with 7.0.12 from virtualbox.org's repository. Every now and then there are teething problems with new kernels or graphics, but I would claim its perfect for my production use, i.e. pass through of USB devices and shared folders.

I started using VBox with Squeeze if I remember correctly, and I haven't got any issues with "disk full" or access problems to USB drives.

Well, I have always avoided the default of using my home drive to store the VMs. From the beginning I have had a separate partition or drive for them. Its easy to configure in the options of the Virtualbox Manager.

Yes. The user needs to be in the vboxusers group. This normally is established during installation of the main package.

And attention to the extension package. Its version has to match the main packages version.

Can't tell you how exactly the Debian build works, I'm not using it. In any case under depends there is a reference to virtualbox-dkms or similar, I think this might do the job in the background.
