thanks, but using the "--no-auto-check-trustdb" does not help. I still
get the error:

$ gpg --verify --no-auto-check-trustdb file.sig
gpg: assuming signed data in 'file'
gpg: Signature made 2019-10-24T21:33:21 CEST
gpg:                using RSA key 88B5AAEE121345AA
gpg: Fatal: can't open '/home/testuser/.gnupg/trustdb.gpg': Operation
