Problem:
When runningĀ sudo apt update
you see the following error message:
Err:14 https://ocean.surfshark.com/debian stretch InRelease The following signatures were invalid: EXPKEYSIG 1DB7590E83C8F643 Surfshark package maintainer <[email protected]>
Solution:
Download the updated Surfshark release package (which contains the updated key from the repository) from the Surfshark website and install the package e.g. using
sudo dpkg -i ~/Downloads/surfshark-release_1.0.0-2_amd64.deb
After that, the error should be fixed and you can run
sudo apt update
again.
