Downgrading dockers

[Jules]

Hi all,

 

Unfortunately, I've updated dockers and my Duplicati docker is bugged.

 

 

How do I downgrade it to 2 previous versions or so?

If anyone has any idea, here is the log:

Sveral things first...

 

First the docker you're using needs to have explicitly labeled prior versions of the docker, wether its by build numbers or by dates. If this is not the situation then there is no previous version for you to rollback to.

 

If that requirement is met, then you need to use that explicit version which works when you configure what docker to setup instead of "latest". I'm not sure how this is handled on the unraid UI, but from the command line you just replace latest with the exact version number.
