I had real problems setting up Myrcoft using the guide including the VirtualBox/Ubuntu Image.
In short: The installation of Ubuntu did not preceede due to some problems with “snaps” which I honestly did not understand (here is more to that).
So for the simple users as me, who use Linux not that often, I figured a solution to that problem, which is using Debian 10 instead of Ubuntu.
This website helped me a lot.
At the moment I got Mycroft running in a FullDesktop Version. The network-server image I tried is not working, there I have some problem with the audiodriver, if someone has an idea, I am very open for suggestions!
some addition help:
I had to install a few things to get mycroft running smoothly:
apt-get install sudo //to install the sudo command
gpasswd -a user sudo //to get your user to be allowed to use sudo, somehow visudo didnt work
sudo apt install git // to get git
and you have to allocate at least 12gb to your virtual hard drive
in the fullimage this should be enough, in the minimal I also had to install pulseaudio, e.g. and apparently the alsa drivers, which I have no real idea how to do that.
hope this helps someone and maybe someone else has an idea how to get the minial image running as well
