I'll let it upgrade when the upgrade is due but I'm not looking forward to this given what I've seen from the new interface. Probably will be messing with profiles as well. Getting ready for more tweaking.

For what it's worth, I installed Chimaera beta as a VBox VM last night to see whether the method I suggested to @manyroads works the way it does under Beowulf, changing the apt repository to:

deb https://download.virtualbox.org/virtualbox/debian bullseye contrib non-free

Unfortunately that didn't work as expected. Not sure if this is because Chimaera is still in beta.

I did manage to install VirtualBox using

dpkg -i virtualbox*.deb

After adding $USER to the "vboxusers" group and a reboot, I noticed only 32-bit is available but I suspect this is simply because I was basically installing VirtualBox in a VirtualBox VM rather than on bare metal (same story with another distro).

@manyroads, for now it looks like you'll have to install the *.deb file using dpkg -i as fsmithred suggested.

UPDATE:

Followed the instructions found over here. This time I did manage to install it from the VBox repo. It should look like this:

deb [arch=amd64] http://download.virtualbox.org/virtualbox/debian bullseye contrib

Regarding virtualbox on Devuan, this is how I go about it (using a perl script):

Add the repository keys:

wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add - 
wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -

Add this to /etc/apt/sources.list:

deb https://download.virtualbox.org/virtualbox/debian buster contrib non-free

Install kernel headers:

sudo apt-get install linux-headers-$(uname -r)

Update repositories and install virtualbox:

sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install virtualbox-6.1

Add $USER to vboxusers group:

sudo usermod -a -G vboxusers $USER

Logout and login again. Should work.

The extension pack can be downloaded from the Virtualbox website and installed manually from Virtualbox or on the command line:

sudo VBoxManage extpack install $file

If you're interested, I've created a perl script to automate this.

Hope this helps.

PS :

edit: tidied up some syntax

I stopped distro hopping years ago and since I don't care about using bleeding-edge software, I don't use rolling releases. I also don't use source-based distributions. So I find myself using Devuan (stable) exclusively on every single one of my machines with only a handful of backported packages installed. I've explored a few other distributions and the BSD family pretty thoroughly out of curiosity. Basically as a way of comparing how they work and as a learning experience. Saw no compelling reason to actually switch even though Slackware and OpenBSD did make a good impression on me. I'm sticking to Devuan as it suits my use case(s) very well.

I stopped using NetworkManager long ago but if you have

network-manager-openvpn-gnome

installed and the NetworkManager service is enabled and up and running then you should be able to just import an existing *.ovpn file using the menus provided by NM's graphical user interface.

That said, these days I just use a Perl script I wrote to select which server I want to connect to and run that in a terminal. Once it's connected, I generally just keep that terminal open. However, you *can* close the terminal just fine since the openvpn process will keep running in the background.

Let's say you hibernate or suspend your machine with the openvpn process still running. Once you resume your session, the process will still be there and it'll reconnect automatically. If you closed the terminal from which you started the process, no worries.

You can always check the connection by running something along these lines:

sudo watch 'lsof -i | grep openvpn'

I do this all the time these days and it works fine.

Hope this helps.
