Hi pallebone,
I've exhausted my attempts to reproduce the implementation of what you have kindly provided as a possible solution to my problems. [2 problems, the error when download updates and the inability to download etcher].
In an attempt to resolve the problems and eliminate what is most probably my ignorance, I have gathered a detailed audit trail .
Instructions
"Please remove (untick) the two repositories with an error in synaptic sources list"
From Synaptic package manager / Setting / Repositories points to repositories Software and Updates, under the tab Other Software I could find neither of the 2 sources you mention, the closest one being https://deb.etcher.io stable etcher, which I unticked and ran the file update it requested.
Before and after screenshots attachments 1 & 2.
Did in Terminal
echo "deb https://deb.etcher.io stable etcher" | sudo tee /etc/apt/sources.list.d/balena-etcher.list
and
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 379CE192D401AB6
and
sudo apt-get update
sudo apt-get install balena-etcher-electron
NB the errors in the last 2 runs.
E: The repository 'https://deb.etcher.io stable Release' is not signed.
and
E: Unable to locate package balena-etcher-electron

I'm out of ideas, can you see a way forward.
My 18.04.2 also won't load Etcher with the error 'not signed'.
