Apt install gives error when using the curl - s command

[poster]

Hi all,

This is the error I get when trying to run the apt install command. What could I try to resolve this? Thank you.

$ curl -s https://syncthing.net/release-key.txt | sudo apt-key add - [sudo] password for user:

gpg: invalid key resource URL '/etc/apt/trusted.gpg.d/home:selmf.gpg'

Those errors look like they’re more about a broken gpg setup than our new key. I’m not sure how to resolve them.

Thanks for your answer. Is this something to do with my computer specifically? I can definitely do a hunt. I’ll have to see what a GPG setup is

OK fixed.

I ran this:

/etc/apt/trusted.gpg.d$ sudo rm home\:selmf.gpg

That removed the existing file (maybe damaged?) and allowed me to run the command again and it worked.

I got the tip from here for anyone in the future : https://serverfault.com/questions/1022078/ubuntu-add-repo-app-key-fails

Thanks again /u/calmh. That sent me in the right direction.

All the best…
