Bug Description
If a sync is needed, then list-current-files now fails as follows:
GPGError: GPG Failed, see log below:
===== Begin GnuPG log =====
gpg: AES encrypted data
gpg: gcry_kdf_derive failed: Invalid data
gpg: encrypted with 1 passphrase
gpg: decryption failed: No secret key
===== End GnuPG log =====
Gpg is complaining because it is not given a passphrase, but the real issue seems to be that the collection is now initialized before the sync, rather than after it, and it is not properly updated, so duplicity looks for a sigtar.gpg file and tries to decrypt it even though it has already been decrypted and stored locally as part of the sync.
Also, the following check can cause a traceback on python 3, since sometimes a ParseResults sets a time, rather than start_time and end_time:
+ return parsed.end_time >= target_
+ parsed.start_time <= target_
Since parsed.start_time and parsed.end_time can be None, it looks as though the code may also behave incorrectly on python 2.

Although the bug has been closed it is still apparent when using the Deja Dup GUI.
Versions:
- Ubuntu 20.10
- duplicity 0.8.11.1612-1
- deja-dup 42.2-1ubuntu1
Steps to reproduce:
- Create a backup of the user home folder to an external USB device
- Install a fresh Ubuntu 20.10
- Open "Backups" (= Deja Dup) and recovery
- Select the USB drive as source -> Next
- Select the latest backup date -> Next
Error message:
GPGError: GPG Failed, see log below:

gpg: gcry_kdf_derive failed: Invalid data
gpg: encrypted with 1 passphrase
gpg: decryption failed: No secret key
===== End GnuPG log =====
Bypassing Deja Dup:
- Switch to Terminal
- export PASSPHRASE=
- duplicity list-current-files file://
Duplicity lists all files - also recovery via Terminal works
duplicity --file-to-restore /home/daniel/.gnupg file://
