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!
