Troubleshooting
Â
Problem: the Portainer page does not load with a “ hostname.local
refuses to connect" error
Solution: this is a known bug in the version of Portainer we must use for the Duckiedrone. The good news is that the error happens seldomly, and once it is solved, it will not happen again. To clear the error:
Open a terminal on your base station
Windows: press the Windows key, type
cmd
, open the command promptMac: Press
Ctrl
+Spacebar
, typeterminal
, openterminal.app
Ubuntu: you should know how to do this
Make sure you are connected to your drone
Type
ssh duckie@hostname.local
password is
quackquack
say yes to whatever it asks regarding permissions and keys - don’t be alarmed by nasty messages of hacking attempts
Type (and execute by pressing enter after each line):
docker stop portainer
docker rm portainer
docker volume rm duckietown_portainer-data
dt-autoboot
Refresh the Dashboard > Portainer page. If the problem has not been solved, try again. It will eventually work.
