Turris Omnia: Updater execution failed: Unable to finish URI

Hi all

I often get mails from my router with folling information:

Error notifications
Updater execution failed:
runtime: [string \"requests\"]:451: [string \"utils\"]:443: Unable to finish URI (https://repo.turris.cz/hbs/omnia/lists/pkglists/luci_controls.lua): Download failed: Could not resolve host: [repo.turris.cz](http://repo.turris.cz/)"

But I do not have any connection problems, beside this.

Playing around with the DNS settings (Use forwarding yes/no, DNSSEC yes/no, etc.) does not help. Deactivating Adblock does not help either.

Any other ideas?

Device Turris Omnia
reForis version 1.4.1
Turris OS version 6.4.2
Turris OS branch HBS
Kernel version 5.15.127

Many thanks for your help.

I had the same problem recently with update from 6.4.0 to 6.4.2.
In my case, however, the connection test test in Reforis displayed some IPv4 connection issues.

I changed the DNS forwarding setting from “Use provider’s DNS resolver” to “CZ.NIC (TLS)”. I might also have rebooted the router, but I’m not sure about that.

As a result, the connection test result was ok and I could perform the update just fine.
After the update, I changed the settings back to the original ones and connection test was still fine, the TO could also still connect to the update server.
