Hi, just tried to follow the video for chromium browser on N2 and have failed at the first hurdle ....

Can you try this command?

Code: Select all

sudo add-apt-repository -S deb http://ppa.launchpad.net/saiarcot895/chromium-beta/ubuntu/ groovy main

That is the command I initially used that generated the unsigned no public key error
removed the apt sourcelist file and tried the command as supplied in your reply again with the same results
If I amend the source list file to add [ allow-insecure=yes ] option I am able to perform sudo apt update
and also sudo apt list chromium-browser shows it available from the ppa repository, as yet I have not issued the install command.

Can you try this command as well?

Code: Select all

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E6A17451DC058F40

Thanks that fixed the problem .... output was

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E6A17451DC058F40
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

gpg: key E6A17451DC058F40: public key "Launchpad PPA for Saikrishna Arcot" imported
gpg: Total number processed: 1
gpg: imported: 1

which has a warning about apt-key is depreciated (not sure if this is the root cause of initial failure)
sudo apt update now works without warnings or errors.
I will continue with the installation and customisation now.

Thanks again for the assistance.

Glad to know this helps, and it will help someone else if one meets the same issue.
