[Bug 1777710] Re: gpg throws out my secret keys after upgrade to 18.04

[Dimitri John Ledkov 🌈]

what are the permissions of /home/psusi ? and /home/psusi/.gnupg ?

it is not safe if .gnupg; or the directory that contains it; are
group|other writable.

new gpg uses keybox, whilst old gpg uses pub/secring.gpg. whenever new
gpg was first executed against this .gnupg the old secring got auto
converted to a keybox and from that point on the secrings & keybox no
longer maintained in sync.

Please check .gnupg/private-keys-v1.d/* folder and if that contains
expected subkeys. If not try to use old gpg to export the subkeys; and
re-import them with a new gpg, such that they migrate into the keybox
structure.

Title:
  gpg throws out my secret keys after upgrade to 18.04

Status in gnupg2 package in Ubuntu:
  Incomplete

Bug description:
  I recently upgraded a server from 16.04 to 18.04 and gpg has started
  throwing out my secret keys.  I even tried deleting the .gnupg
  directory and re-importing or just copying the secring from another
  working system, and it still throws out the secret keys.

  Working system:

  C:\Users\psusi\AppData\Roaming\gnupg>gpg --version
  gpg (GnuPG) 2.0.28 (Gpg4win 2.2.5)
  C:\Users\psusi\AppData\Roaming\gnupg>gpg -K
  C:/Users/psusi/AppData/Roaming/gnupg/secring.gpg
