Unable to add ANY PPA

[salil.work]

Hello,
I am running Linux Mint 19.1 Tessa (base ubuntu 18.04) on my laptop. I am unable to add ANY PPA to the repository (for example: sudo add-apt-repository ppa:geany-dev/ppa). Whenever I try to add a PPA to the repository, I end up with a message:
gpg: keyserver receive failed: Server indicated a failure

I am not sure whether the problem is related to Linux Mint or to its base which is Ubuntu 18.04. Hence I am posting my problem in this forum.
Please note that I have been able to add the required repositories on my second laptop which also runs Linux Mint 19.1 Tessa.

Any help would be greatly appreciated.
Thank you

Moved to Mint.


I don't see any packages for Bionic listed, the newest appears to be for 17.10. There is a new version for 14.04 which reaches EOL soon. https://launchpad.net/~geany-dev/+archive/ubuntu/ppa

Hi and welcome to the forums

Please post the output of this command:

cat /etc/resolv.conf

Thanks.

Thanks for the reply. But I was able to install Geany (1.34) on another machine which is running Mint 19.1 using the PPA. The problem is not limited to a single package. I get the same error whenever I try to add a PPA using sudo add-apt-repository. Here is another example (sudo add-apt-repository ppa:fenics-packages/fenics). I am able to install Fenics on my "other" machine but not my laptop.

Are both machines connected to the same network and have exactly the same network settings?

Check /etc/resolv.conf because gpg requires an entry in that file in order to work correctly (at least according to this post https://www.reddit.com/r/archlinux/c...ted_a_failure/)

Another user resolved it here: https://unix.stackexchange.com/quest...ated-a-failure and https://prnt.sc/nalecj

Hope this helps.

The machines are connected to the same network. The machine on which I do not have a problem has a wired network connection while the one which is giving me problems has a wireless network connection.
