Looks like some dependencies are missing like this one for example.

I might have a look at it during the following days if nobody else do it in the meantime.

  • I hope this is how you check a package? I am still new to eopkg

sudo eopkg check duplicity
Checking integrity of duplicity OK

  • Please advise how I can assist

You can't assist. Someone has to review the package.
I might be wrong but I have the impression that it was only used as a dependency of deja-dup (R609) but not as a stand-alone version.

@krios123 this is now about two years old is there any work around?

@marxistvegan 2 years old ? The problem was reported yesterday and patch is submitted today.

@kyrios123 my apologies I misread it completely... thanks

@kyrios123 It looks like duplicity is still missing the python-monotonic dependency? Duplicity was still crashing for me. Installing python-monotonic solved it

Nope it is not I did replace python-lockfile by python-fasteners in this commit 85cd57e5e0b4 and as you can see here python-monotonic is a dependency of python-fasteners so when you install duplicity, the magic happen as you can see on the screenshot

@kyrios123 Thanks for the clarification. Looks like I've build and installed python-fasteners locally myself to fix this. And then the new package you have added wasn't installed. Sorry for the confusion
