cli: Installation failed on Ubuntu 20

Fixed it Using: sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key C99B11DEB97541F0 adding hkp:// and :80 did the trick

reference: https://unix.stackexchange.com/questions/399027/gpg-keyserver-receive-failed-server-indicated-a-failure

Facing this. No VPN on my end. Ubuntu 20.04

You only mentioned the addition of port :80 , that alone didn’t work. hkp:// was essential too.

when I tried to access the link https://cli.github.com/packages, I see that it is not found.

You cannot visit this link in your web browser. That will always result in a “Not found” page, and that is expected.

To configure your package manager to download packages from that location, you must follow the instructions here: https://github.com/cli/cli/blob/trunk/docs/install_linux.md#debian-ubuntu-linux-raspberry-pi-os-apt

If that doesn’t work, please provide more information about what you’ve tried and what doesn’t work. Most importantly, check your /etc/apt/sources.list.d/ directory for signs of having properly configured our package repository.

It needs upgrade , contact me back if you want my help okay

@Satwato Thanks a lot. This really fixes the issue.

Could it be that these are legitimate network errors on your end? Does the problem persist over multiple retries spread out over an hour?
