Fontconfig error: No writable cache directories

[warg]

Hello,

I updated my Collabora instance and noticed that during the update and shutdown/startup process both times the app complains several times about:

Fontconfig error: No writable cache directories

Seems like some caching directory is read-only.

Best Regards,

Have you adjusted the app config somehow? At least on a fresh instance I can't reproduce the issue.

In the app settings I have just enabled the "Disable indexing" option for robots.txt and in coolwsd.xml I changed nothing.

I just saw that in the Collabora settings (after logging in to the app) I saw this string:

[a-zA-Z0-9_\-.]*

Doesn't look like something I have maintained. Maybe my previous setting was overriden by an update? Sounds wrong to me because the hostname part is completely missing. Beside of that, I doubt it's related to the above error.

I also noticed that the fonts directory of Collabora is empty.

The fonts directory is only for custom fonts to place https://docs.cloudron.io/apps/collabora/#adding-fonts

The regular expression actually has a bug, which is then fixed with the next package version. But this should not be related to your original cache issue, which I still can't reproduce.

Since the app as such is basically stateless, if you haven't made any special setting adjustments, can you try to reinstall it to see if you still encounter the caching issue?

I have sent you the full log of a new/fresh installation via email.

I have the same error, albeit with the built-in CODE Server. Trying to open a document results in the app being non-responsive.

EDIT: The non-responsiveness was due to not enough "mdm-workers"

Support couldn't reproduce it for now so they just ignore it for now as it's not critical. Maybe someday we have an idea on what causes this.
