Seafile won't start after 9.0.9 update

[isidoreisou]

My YunoHost server

Hardware: Kimsufi KS4
YunoHost version: 11.2.5 (stable)
I have access to my server : Through SSH + through the webadmin

Description of my issue

After updating Seafile to 9.0.9~ynh1, it’s not starting anymore.

• seafile service won’t start.
• seahub service won’t start.
• 502 Bad Gateway on the webpage of my instance

A file seems to be missing or misplaced, similir to this problem: [Seafile] - Internal Server Error - #8 by aga, but I would like your advice before trying anything.

Thank you!

Here is the seafile service hastebin logs.

Update:

seafile-server-latest was pointing to a missing folder:

lrwxrwxrwx 1 seafile seafile 20 Sep 25 2022 seafile-server-latest -> seafile-server-9.0.2

I’ve updated it:
ln -sfn seafile-server-9.0.9 seafile-server-latest
and now both services start, but the css on the web interface seems missing.

Here is the solution:

First fix where the seafile-server-latest folder point:

ln -sfn seafile-server-9.0.9 seafile-server-latest

Then

setfacl -m user:www-data:rX /opt/yunohost/seafile/seafile-server-9.0.9
setfacl -m user:www-data:rX /opt/yunohost/seafile/seafile-server-9.0.9/seahub 
setfacl -R -m user:www-data:rX /opt/yunohost/seafile/seafile-server-9.0.9/seahub/media

Found the solution here:

after update cannot access application no more
