Backup duplicity error file not found. Backup never run

Richard378 · January 28, 2024, 4:42pm

I am getting a backup error with duplicity. I have rerun mailinabox and it does not fix it. It is a fresh install and backup never worked.

I get the error:

[Errno 2] No such file or directory: ‘/usr/bin/duplicity’

With any backup I try, local and backblaze B2. I can’t backup becuase of this. I tried running the script directly cd maininabox managment/backup.py and get the same error.

How do I fix this? Reruning sudo mailinabox does not work.

Looks like yesterday’s release on the duplicity gitlab PPA is missing the binary. I started another thread just a couple of minutes behind you. I’ve opened an issue on the duplicity gitlab page.

Python 3.10.12 breaks backup.py

Hi All, I am looking into this, but have noticed after yesterdays updates to… python in Ubuntu 22.04.3 that the duplicity command line options '--gpg-options:' previously used by MIAB no longer work and is now expecting a different argument. `Aug 9 09:34:05 box start[2170]: duplicity collection-status: error: argument --gpg-options: expected one argument` I suspect the duplicity isn't the cause as there is only one argument used in the backup.py script '--cipher-algo=AES256"' . Upon trying to switch back to local backups I also receive an error: in the Admin page `<!doctype html> <html lang=en> <title>500 Internal Server Error</title> <h1>Internal Server Error</h1> <p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p> `

I noticed downgrading to 0.8.21 fixes my problem. as per this bug.

I emailed the PPA maintainers about this bug.

Down grading the duplicity version fixes the error in the panel, but running backup.py directly fails.

Did you get anything back from the duplicity request - my box is now complaining of the binary missing as well?

Not sure how to proceed - any help or information would be greatly appreciated!

Thanks!

Try downgrading duplicity to this version: 2.1.5-ppa202312281721~ubuntu22.04.1. It’s what was installed prior to the latest.

Version 0.8.21 will not work with the recent versions of MiaB.

I’ve posted a workaround in the other thread:

This is the issue.

In another thread @asm0dey mentioned where apt kept cache of the installed packages.

Here’s how rolled back to previous version.

cd /var/cache/apt/archives
ls -1 duplicity*
duplicity_2.1.5-ppa202312281721~ubuntu22.04.1_amd64.deb
duplicity_2.2.0-ppa202401271616~ubuntu22.04.1_amd64.deb
sudo apt remove duplicity
sudo apt-get install $PWD/duplicity_2.1.5-ppa202312281721~ubuntu22.04.1_amd64.deb  
sudo apt-mark hold duplicity

IMHO more stable version of duplicity would be better option than Personal Package Archives, but quick look at Duplicity website suggests that the one of the “stable” methods might be more stable, than the PPA.

I think I’ll keep the duplicity package on hold for a while.
