I have implemented the suggestions for the update. DDNS turned off and undone the changes for DNS over TLS on the Knot Resolver. Update went through clean and everything works fine. Now I’m looking for the option to change the default DNS (in my case to Cloudflare).
Edit: according to Mail the foris-tls-plugin was uninstalled (some packages at the end of the mail)
Is it related to it? Everything works so far, only this thing makes me suspicious
##### Restart is needed #####
The system was updated, but some changes will take effect only after reboot. Please reboot the device.
The device will be restarted automatically on Friday, December 14 at 03:30 AM. • **Removed package foris-tls-plugin-l10n-de**
• Removed package python-libatsha204
• **Removed package foris-tls-plugin**Where is this menu? Or was it really uninstalled? Can I reinstall it?
Best regards!
