Public key not available on update

Post by koyut »

I tried updating through apt-get update and been having these errors. This is a fairly new system and used v158 strech image.

Not sure if I did the right way but it seemed to fix the issue.

Code: Select all

sudo apt-get install dirmngr
Then followed installing the keys from:
