Fixing no public key errors in linux - SpookyZalost - August 31st, 2021
So while I was setting up Pop! OS to do some software compiling I ran into a few issues.
the biggest of which was an error that looked like this: (NO_PUBKEY)
now what that means is either through network issues or other problems the public key for a repository to match the key to safeguard the repository is not available.
in my case it was because I needed the Xenial repositories for some libraries I need to compile stuff.
I tried a few different fixes but nothing worked so I went and tried the most manual and direct way short of going into they keychain and manually dropping it in there, provided i had the key...
I used the following Command, edited for the keys the error indicated I needed.
sudo apt-key adv --keyserver hkp://pool.sks-keyservers.net:80 --recv-keys THE_MISSING_KEY_HERE
you need to do this for each key missing but it works well, hopefully this will prove useful to people looking for how to fix this.
