Just downloaded and installed "master-r14947-0f7a3288e1-20201115 (ath10k-ct) " today.
After installation (clean install with rest of settings) I logged into the the Luci interface, set up my router passwords and set up wireless names, channels, passwords, etc. After this I then went to System, then Software, then hit the Update Lists button. Tried to find the "Stubby" package but it appears to be missing.
I had DNS over TLS working fine via the instructions found here: [Tutorial] [No CLI] Configuring DNS over TLS with LuCI using Stubby and Dnsmasq. Since I can not find the "Stubby" package I am unable to install DNS over TLS as I had before.
Am I missing something.
