An unexpected problem hit me with Mint. I never would have thought that a system which found drivers for a whole bunch of devices on its own would be unable to set up a simple PPPoE connection.
Here’s what happened: I connected to a local network that provides internet via PPPoE. I tried to configure it through NetworkManager โ no luck. Eventually got it working with the console tool pppoeconf, but for some reason NetworkManager then started saying my network card was no longer managed by it. (A few reboots and a reset of /etc/network/interfaces later, it started managing it again.)
