GPG can’t decrypt my data because of an invalid packet
I have an encrypted data containig some of my data that I am unable to decrypt. It is archived with tar, compressed with gzip and encrypted with gnupg. Today I tried to decrypt it with gpg and it failed, even though I have the the password. It is correct (gpg doesn't complain about it). I also checked older backups of the same archive (from different hardware) and I got the same result.
gpg --list-packets produces the following output:
gpg: AES.CFB encrypted data
gpg: encrypted with 1 passphrase
gpg: decryption failed: Invalid packet

:literal data packet:

Is there anything else I can try in order to decrypt my data?
