For those who have noticed, updates to Debian have been failing for the last several days:

$: sudo apt update

To correct, run the following:

Code: Select all

rpi-rw
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 0E98404D386FA1D9
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 6ED0E7B82643E131

Results:

Code: Select all

Note: there may be other solutions to this problem, but the information currently available on the "Internet" on this matter is either stale or misleading or way too involved, and all of them ultimately ended up being dead ends. By trial and error, the above is the simplest solution. It works for both Buster and Bullseye implementations.

Good day/night, colleagues.

@KN2TOD , big thanks for this thread.

I have an experience on my DSTAR & DMR hotspots here. Both are Pi-0 devices.
When I logged to both of them, I have an error to add new public keys for getting further updates. See that:

Code: Select all

root@pistar-dmr(rw):rc3c# apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 6ED0E7B82643E131
gpg: relocation error: gpg: symbol ``▒▒▒▒▒▒ version GCRYPT_1.6 not defined in file libgcrypt.so.20 with link time reference

gpg: relocation error: gpg: symbol ``▒▒▒▒▒▒ version GCRYPT_1.6 not defined in file libgcrypt.so.20 with link time reference

I used a command 'apt upgrade' like this:

............... etc...

Please, wait until upgrade is done.
Then you can use both commands to add new keys as KN2TOD wrote in 1st message of this thread.

Code: Select all

So, all means that you have to upgrade the system, then add new keys. Then update command works well:

Code: Select all

root@pistar-dmr(rw):rc3c# apt update
Hit:1 http://raspbian.raspberrypi.org/raspbian buster InRelease
