Ubuntu VM from Tutorial does not start

[marcusdots]

Expected behaviour

I am on Debian. I tried to follow the tutorial in README.md and install an Ubuntu VM.

Actual behaviour

Ubuntu VM does not start.

Steps to reproduce the behaviour

$ time ./quickget ubuntu 22.04

I think we probably need an FAQ in the readme for this type of "issue" Along with all the other similar issues.

Something in the issue template too:

We need to remind people to check all the closed issues, not just the open ones.

Plus something to tell users not to instantly presume there is something wrong with quickemu when their first install fails to work. Something to tell them to test their Host setup is up-to-date and to test it in various scenarios too.

Edit: Something like this, that I have just added https://github.com/TuxVinyards/qqX/wiki/FAQs-and-Help

I think your target audience are qemu novices. At least that is what draw me to quickemu. qemu is powerful but hard to learn and I was hoping that the quickemu abstraction would provide an easy start.

That being said, I think a KISS VM to verify your host system would help new users.

In my case quickemu was trying to setup pulseaudio and failed. I think a stripped down VM with as least as possible assumptions about the host system would ease debugging issues.

My fix is ubuntu-22.04.sh
