Error: no_fontconfig
What can I do to stop having this error message?
You can either uninstall it or address the missing requirement.
See:
- Collabora Online - Built-in CODE Server - Apps - App Store - Nextcloud
- GitHub - CollaboraOnline/richdocumentscode: Built-in CODE Server app
But without more information (such as that requested by the support template) about how you have Nextcloud installed, it’s impossible to be of further help. One approach would be to run Nextcloud in a container, with all of the requirements. There are other approaches.
