[Question #690828]: Random broken pipe GPGError: GPG Failed

 

New question #690828 on Duplicity:
https://answers.launchpad.net/duplicity/+question/690828

Im running duplicity 0.8.13

About 30% of my incremental backups fail with the message:

GPGError: GPG Failed, see log below:
INFO: ===== Begin GnuPG log =====
INFO: gpg: using "XXXXXXXXXXXXXX" as default secret key for signing
INFO: gpg: signing failed: Broken pipe
INFO: gpg: [stdin]: sign+encrypt failed: Broken pipe
INFO: ===== End GnuPG log =====

This is really annoying, --num-retries has no effect it will abort on first try always.

If i rerun the backup it succeeds.

Also i dont know how the offsite storage will end up, how does duplicity manage aborted backups ? 

Will they be cleaned automatically next run, will they be cleaned at all with next full backup or do they stay forever.

I could run a while loop until duplicity succeeds (exit status 0) but i dont know if this may break things.

Anyone knows why that gpg error happens and knows a solution for it ?
