Running Ubuntu 12.04 - looking at the PCmanFM site it says the latest version is 1.2.3
(from 14 Oct. 2014) however my version in Synaptic says it is 0.9.10-0ubuntu2
with no option to upgrade.
I have also tried installing with
sudo apt-get install pcmanfm
and got the message:
pcmanfm is already the newest version.
Could someone please explain this?
