I have (more precisely, my employer has) a machine running Ubuntu 14.04 LTS, which comes with wpa_supplicant version 2.1. There are improvements in wpa_supplicant 2.5 which I believe may help with some wifi issues this machine is suffering.
According to dpkg -S, wpa_supplicant is in the wpasupplicant package, but sudo apt-get upgrade wpasupplicant tells me I already have the latest version available.
Is there a PPA in some standard place that would let me bring wpa_supplicant up to version 2.5? Or is it better to build from source? Or is there something else I should be doing?
(The less drastic and invasive the upgrade procedure, the better for us: this machine is actually on someone else's premises and we can connect to it only via wifi. So it would be sad if trying to upgrade wpa_supplicant had the effect of breaking its wifi connection. A brief interruption of connectivity is fine, though.)
