So, I can’t do apt-get update due to the Emlid repository issue of "no longer signed…therefore disabled by default. Then I tried bypass of Emlid repository but upon re-boot, all my USB ports, key board and mouse, are killed.
Then I tried to SSH into my RPi4, but Like many others, I can’t enable wiFi in order to SSH into RPi4 using Putty (supposedly because of an unsolved HDMI/wiFi interference issue on RPi4) . Then I tried to access my RPi4 remotely over the internet using RealVNC (because I can still access the internet over my 5G connection), but because I can’t do apt-get update I can’t enable RealVNC.
Emlid, To start with, Please fix the Emlid repository issue as soon as possible. When will this be fixed?
