It is now working. Problem was, that I first tried to use the "lkhjpoqwrpoqfjiah.key" files below ".gnupg/private-keys--v1.d/, which did not work. Then, during testings, I changed permissions of .gnupg, which led to a new error. Reverting this, I tried "gpg -K" and then saw the keys with its name. Then I could export the keys using the correct syntax (name of the key, not some filename). Such I got a new file, which could be imported into thunderbird. So, one mistake led to another, however, now its working and I learnt something. Thanks for all the help.
