Calibreweb failed to start after update to Yunohost 12

What type of hardware are you using: Virtual machine
What YunoHost version are you running: 12
What app is this about: CalibreWeb

Describe your issue

Following upgrading my Yunohost instance to version 12, calibreweb is failing to start. It looks like some files are missing. I’m hesitating to reinstall the app and loosing all my books. Maybe there is a problem with the new version of Yunohost.
In case of someone has an idea, thanks in advance.

Sounds like the python venv was recreated …

Possibly it should be as simple as force-upgrading the app to regenerate the venv I believe : sudo yunohost app upgrade calibreweb --force

Hi,
thank you for your answer. I did your commande, but I had this error during execution:
https://paste.yunohost.org/raw/acimahudis

It results by uninstalling my calibreweb instance.

I tried to reinstall it in Yunohost, and here also, I have an error and installation failed:

It looks like that there is a python problem with this new version of yunohost. Is somebody successed to have calibreweb installed with Yunohost 12?

Looks like gcc is not installed on your system. Can you try installing apt package build-essential prior to installing Calibre Web? The command would be

sudo apt install build-essential

Super, it was that. Thanks a lot!

Ok, so this needs a package fix…
