I installed VirtualBox form the official website but it fails to start any VMs
Trying to follow the instructions doesn't help.
I also followed this guide and this to try to solve it but didn't make any difference.
I'm running out of ideas. Anyone knows how to solve this? Thanks for the help!
I find it quite disappointing that supposedly stable versions of Ubuntu and VirtualBox don't work out of the box with clear installation instructions
Virtualbox uses a "kernel module" to do its thing.
Just as the text says above, you haven't got the tools to create that module.
SO: Your Virtualbox installation is not complete...
$ sudo apt install build-essential # will install gcc and make
On my 20.04 Ubuntu I have
ii perl
ii perl-base
ii perl-modules-5.30
... included in the output of:
$ dpkg -l | grep -E "^ii +perl[- ]+"
... which I believe to be the complete base of perl (I may be wrong).
And those ii's - tells they are actually installed and I suspect that is the case in your 22.04 too.
( ii --check--> $ dpkg -l | grep -B 100 "+++-").
When you have done/verified the above; reinstall virtualbox.
