(ubuntu 18.04.1) i installed etcher, rebooted some time afterwards, and got this:
when i put
sudo apt-get update in the terminal, i essentially get the same thing:
E: Type 'sudo' is not known on line 1 in source list /etc/apt/sources.list.d/balena-etcher.list
E: The list of sources could not be read.
anyone know a fix? i’m pretty pissed.
