Recently, I tried to add a source to my Raspberry Pi (running the latest stable update). Suddenly, it crashed, and, despite many restarts of the machine, I cannot access the web ui (just getting a failed to connect to server error in safari). I tried updating to the prerelease, but nothing seems to help too much. Sometimes it gets to showing the "Welcome to Channels" screen, but never further.
Any advice? I can still SSH into my machine so I can run commands. Thanks!
