Disable Chromium "Can not update Chromium" Window Notification

This Bug seems to be floating around Debian and Raspbian already since Chromium 76.

From the Debian Report I understand it should be fixed with Chromium 78 and the commandline option --disable-component-update should disable it.

But from the thread in the Raspberrypi.org Forums it still seems to appear in Chromium 78 at least on Raspbian. So there the following workaround is proposed:

Create a file /etc/chromium-browser/customizations/01-disable-update-check and set its content to

CHROMIUM_FLAGS="${CHROMIUM_FLAGS} --check-for-update-interval=31536000"

Or as a copy&paste solution:

sudo touch /etc/chromium-browser/customizations/01-disable-update-check;echo CHROMIUM_FLAGS=\"\$\{CHROMIUM_FLAGS\} --check-for-update-interval=31536000\" | sudo tee /etc/chromium-browser/customizations/01-disable-update-check

It effectively disables the update check for 1 year, until then a fix should have been distributed.

Try this flag

--simulate-outdated-no-au='Tue, 31 Dec 2099 23:59:59 GMT'

You can set a future date. This will let chromium think that it shouldn't be outdated until this date and therefor won't show the outdated message.
