I just installed Ubuntu 14.4 LTS on 32-bit Dell Inspiron 1545 (that was actually pre-packaged with Ubuntu 10.x in about 2010).
For some reason, it doesn't have the capacity to scan for nearby wi-fi network.
I tried adding wi-fi network manually, but Ubuntu still acts as if it doesn't know about wireless
When I try executing:
sudo apt-get install linux-firmware-nonfree
I get error:
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
