[synapse] Service matrix-synapse will not start

Hi there.

My YunoHost server

Hardware: Self-Hosted Proxmox VM server.
YunoHost version: 4.0.4 - Just migrated 2 days ago.
I have access to my server : Through SSH
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : yes
If yes, please explain: Just migrated up to version 4 - 2 days ago.

Description of my issue

“Synapse Matrix homeserver” will not start and fails to auto-start as well.
I have just migrated up to v4 and Buster.

I have a look at thread below on permissions, but this does not seem to be the case.

Any suggestions please.
Thanks.

Hello,

I also know a person in this situation.

Is a solution possible?

Thank you.

Best Regards

I think that’s because the python’s virtualenv for synapse needs to be recreated (assuming it’s python…)

Maybe an upgrade of the app can solve the issue

I have the same problem and I have opened an issue here: https://github.com/YunoHost-Apps/synapse_ynh/issues/209

Hello,

I have the same problem. When i run the command :

systemctl status matrix-synapse.service

it returns :

● matrix-synapse.service - Synapse Matrix homeserver

   Active: activating (auto-restart) (Result: exit-code) since Sat 2020-08-15 19:55:18 CEST; 1s ago

Thanks

Thank you Josue.

This was very helpful.
I ran a backup and then ran the upgrade command.

yunohost app upgrade synapse -u https://github.com/YunoHost-Apps/synapse_ynh/tree/master

My Synapse-Matrix is now up and running.
Thank you for your support.
