Export & Import of GPG Keys  

To remedy a case of corrupted gpg keys on Linux (if you have the GPGKeys elsewhere):

  • First create a ‘Backup’ [on Windows, via the GPG4Win > GNU Privacy Assistant (GPA)].

  • Next, copy the backup file to Linux & on Linux, run: gpg –import /path/to/backup/file.

  • Lastly, set the necessary level of trust:

    $ gpg --edit-key <uid>;
    gpg> trust
    1 = I don't know or won't say
    2 = I do NOT trust
    3 = I trust marginally
    4 = I trust fully
    5 = I trust ultimately
    m = back to the main menu
    Your decision? 1
    gpg> quit

Thankfully, a trusted Windows machine had GPG4Win which allowed me to export the key and saving my day!
