Dasher not running anymore after update/upgrade to 0.42.2

Dear Forum,
my dasher on RPI is not starting anymore with “dashing start” but comes back with

pi@hassbian:~/hadashboard $ dashing start

scheduler caught exception:

after running
$ sudo apt-get update
$ sudo apt-get -y upgrade
$ sudo systemctl stop [email protected]
$ sudo su -s /bin/bash homeassistant
$ source /srv/homeassistant/bin/activate
$ pip3 install --upgrade homeassistant

$ sudo systemctl start [email protected]

Home-assistant is 0.42.2 is running fine

Thanks for your support

Dasher itself is no longer a supported project. This one of the reasons that HA Dashboard v2 was created.

You need to move to the new beta.
