sudo nano /etc/apt/sources.list

comment out the following line so that you activate the backports repo (or add it if it's not already there):
deb     http://deb.devuan.org/merged ascii-backports main
https://devuan.org/os/etc/apt/sources.list

you can check backported packages here: https://pkginfo.devuan.org/

since you use backports, you will have to resolve a few dependencies. aptitude is better than apt-get or apt for this purpose. on the other hand, it is not a good idea to mix apt-get and aptitude. it may be wiser to stick to apt-get for now.

Everything is in /etc/apt/sources.list, there is no margin for error. I did not have access to a computer, nor did I have to tweak sources.list in the past. You are right to clarify this but I don't do anything until I read it in the documentation and experimented in a virtual machine.

I understand that a regular update such as sudo aptitude update && sudo aptitude safe-upgrade is only going to fetch the required packages from backports but everything I read made me think I had to close the valve. The following links refer to the official documentation:

• no security support: https://backports.debian.org/FAQ/

• risk of incompatibilities with components from the stable version: https://backports.debian.org/Instructions/#index3h2

• enable them on demand only: https://devuan.org/os/etc/apt/sources.list

Well, let's say it is highly confusing for something that is actually quite simple. It's ok to keep backports enabled if I fetch one package but upgrading everything is not recommended: sudo aptitude update && sudo aptitude -t ascii-backports upgrade
I am going to stick with sudo aptitude update && sudo aptitude safe-upgrade (backports enabled)

1) no need to uninstall a package
2) indeed, everything is on devuan.org but also in /etc/apt/sources.list
3) since there is no security support for packages from backports, all I have to do is install the backported package, uncomment those lines, and update-upgrade my system as usual?

Oh, I do not use desktop files on Linux but it comes in handy in that case!

I run QEMU in a virtual machine to test it. I do not install new packages on my hard drive until I know what they can do. I think I am going to use QEMU without virt-manager after all. Thank you!

Thank you guys. I appreciate it. Basically, you have installed qemu sudo aptitude install qemu , loaded kvm sudo modprobe kvm-intel and then entered this command, right?

I forgot to mention that I use qemu with virt-manager (because I did not want to learn how to use qemu). I get the message above with qcow2 images, while ISO images work without having to intervene.

@clint.barton Let me guess: you are Dutch?

Some Skylake processors such as Intel Core i5 6300HQ don't boot Linux either. I guess we should avoid everything that is Lake related.

Hello

I can tell you one thing: do not buy a Microsoft Surface if that's what you mean? They have terrible Linux support and you might miss a few functionalities. You want Linux to work out of the box which is understandable so do not buy one of those.

Any computer will do as long as it does not have a dedicated graphic card. It makes things much easier after the installation. Also, I would not go for Devuan on a brand new laptop because there are distributions with 4.18 kernels now. I would install Gentoo with OpenRC and come back to Devuan when the next stable version is released.
