Drivers not correctly installed on Ubuntu GNU/Linux 16.04

[Obijuan]

In Ubuntu 16.04, in some computers, the drivers is not correctly installed

I've checked it with the following commands:

$ ls /etc/udev/rules.d/

and the file 80-icestick.rules should not appear (as the driver is not installed)

Now, I execute icestudio and enable de driver. It ask me for the password

If I check again, the 80-icestick.rules file has not been copied into /etc/udev/rules.d

If I install apio and execute it by hand, then driver is correctly installed:

$ apio drivers -e

$ ls /etc/udev/rules.d/
70-snap.core.rules 80-icestick.rules 99-anbox.rules

I should notice that this bug is not present in all the ubuntu 16.04. I've confirmed it in one laptop, but in another one with the same ubuntu version the bug was not present

It only happens in the AppImages, because it can not copy the file "80-icestick.rules":

cp: cannot stat '/tmp/.mount_DvE0fZ/usr/bin/resources/config/80-icestick.rules': Permission denied

Solved using echo instead of cp.
