Description of my issue

For some weeks, I’ve been having some issues with synapse, it failed to being backed up, then stopped working. Then I restored it to the last backup, then occurred the same issue again after some days.
I thought updating it from 1.59.0~ynh1 to 1.69.0~ynh1 may resolve the issue, so I restored it to latest working version, performed bullseye upgrade and tried it, but the synapse upgrade keep failing.
The error log seem cryptic to me, rather empty.

yunohost app upgrade -F synapse

Any hint or suggestion in any direction would be deeply appreciated :slight_smile:

It sounds related to the fact that you probably increased the password policy to enforce lower/uppercase chars etc, but probably the mechanism that generates a random password for that special synapse user doesnt generate such a password (but it is a 30-char long password tho) …

One workaround can be to temporarily reset the password policy while upgrading/install/restoring the app I suppose

Yo @Aleks two times in one day I’ve got to thank you so much. Again right on the spot. I was seeing this log about password policy and I couldn’t figure out what it could have to do with upgrade and it’s failure.
Thanks a lot, indeed running the following did the job perfect and synapse upgraded fine :slight_smile:

sudo yunohost settings set security.password.user.strength -v 1
sudo yunohsot app upgrade -F synapse
sudo yunohost settings set security.password.user.strength -v 3
