I'm having the same problem

Yunohost 11.0.11
Hardware: Raspberry Pi 3B+

Any way to fix this by hand ?

Trying to fix this with the manual.

Go to the Seafile home: /opt/yunohost/seafile/seafile-server-latest, and switch to root user with sudo su.

The difficulty is that sudo -u seafile ./seahub.sh start hides the python errors, and only shows "seahub failed to start". From this thread it says you can use the deprecated sudo -u seafile ./seahub.sh start-fastcgi to troubleshoot, because it has a similar behavior and print python errors. This help me find the missing packages.

To install the python package, you should not use the bare sudo pip3 install ... command. The python packages for Seafile belong to the seafile home user (/opt/yunohost/seafile/.local/lib/python3.9/site-packages/). To modify this local package repository, the command is sudo -u seafile pip3 --user install ... (you execute the command as the user "seafile", and update the local packages).

Another information, is that some packages are present in /opt/yunohost/seafile/seafile-server-9.0.2/seahub/thirdpart/. The python packages should match the versions of these files.

It may be different for others, but for me, I had to do

 sudo -u seafile pip3 install --user cffi==1.15.0
 mv seahub/thirdpart/PIL/ seahub/thirdpart/PIL_old
 seahub/thirdpart/MySQLdb/ seahub/thirdpart/MySQLdb_old

The mv command also solve conflicts I think, I got this from the same thread.

And problem was solved. I also issued the command sudo -u seafile pip3 install --user django==3.2.* Pillow pylibmc captcha jinja2 sqlalchemy==1.4.3 django-pylibmc django-simple-captcha python3-ldap mysqlclient pycryptodome==3.12.0 cffi==1.15.0 lxml from the manual, downgrading django from 4.1.5 to 3.2.16 and SQLAlchemy from 2.0.0 to 1.4.3 but I'm not sure it had impact. Beware that in the manual they tell to use cffi 1.14.0, but it is the 1.15.0 version that matches local files.

I can confirm the error is gone with the current testing branch.

Hello,

Thanks !

I did try the testing branch, and it is not installing as of today. To fix it, and mostly helped by matthiasbe's post :

1/ install seafile without removing on failure : yunohost app install seafile --no-remove-on-failure

2/ Fix python's packages : sudo -u seafile pip3 install --user django==3.2.* Pillow==9.0.1 pylibmc captcha jinja2 sqlalchemy==1.4.3 django-pylibmc django-simple-captcha python3-ldap mysqlclient pycryptodome==3.12.0 cffi==1.15.0 lxml

3/ Confirm startup as no more module issue and is working in normal-mode :

root@app:/opt/yunohost/seafile/seafile-server-9.0.2# sudo -u seafile ./seahub.sh start-fastcgi

Starting seahub (fastcgi) at 127.0.0.1:8000 ...
Unknown command: 'runfcgi'
Type 'manage.py help' for usage.
Error:Seahub failed to start.

root@app:/opt/yunohost/seafile/seafile-server-9.0.2# sudo -u seafile ./seahub.sh start

Starting seahub at port 8000 ...

Seahub is started

Done.

4/ Cleanup and startup :

sudo -u seafile ./seahub.sh stop

systemctl start seahub
systemctl status seahub
