As reported in
a pubkey could not be imported and a new keypair could not be created with Gpg4win 3.1.13
it worked with 3.1.10 before.
The problem is a non-ASCII character in the user name of the windows account.
How to reproduce:
- Install Gpg4win (as User with Administration Rights)
- Add another account with an Umlaut,e.g. "Maus Münster" or "Östern" (Short way on Windows 10: Settings/Einstellungen -> Kontos -> Family and other Accounts -> weiteren Nutzer. Kenne Ameldedaten nicht -> lokales Konto)
- Login as other user, try e.g. gpg -v --quick-gen-key irgendwas after the acceptance of passphrase the error message is Schlüsselerzeugung fehlgeschlagen: No such such file or directory.
[Please note that although this is a regression in GnuPG 2.2.23 the actual problem existed for much longer and made it impossible to use Unicode account names or other file names under Windows unless the name could be represented by the current one-byte code page.]
