[help] rollback to a previous version of kresus

Hi,

Big troubles with the new version of kresus. javascript errors, and balances of almost every accounts are totally fucked up...

I would like to go back to previous version. At least to make a backup of the database. I was using a docker image bnjbvr/kresus-nightly:prod

What I tried.

git clone https://framagit.org/bnjbvr/kresus && cd kresus
git checkout 0.12.0
docker build -t myself/kresus -f docker/Dockerfile-stable .

But I get 0.13 version. Could you forward me with the procedure to get previous version using docker ?

Thanks much

J.
