You were right, I need the ath9k driver package.
I did something wrong during the first fresh re-install. I first updated to
the new kernel, and then I tried to run your install.sh script. This failed
with some error because a file was not available. (I forgot to write it
down...)
In an overreaction I did not manually copy the files to the /lib/fw directory
but re-installed the Trisquel again.
This time I first copied the firmware files and then updated the kernel. I
did not run the install.sh script. Everything works fine and I restart the
computer.
- Now, I pull the latest Trisquel updates and restart the computer again.
- After that I ran 'sudo apt-get install linux-image-generic-lts-belenos'
which executed without trouble.
- After that I ran 'sudo apt-get remove linux-image-generic linux-image-3.2*'
which prompted me again to free *445 MB*. This time I halted the command.
Here's a screenshot: [] will update later, I have reached my CloudApp limit.
It's German and says that the mentioned packages will be removed.
