changing from bullseye to bookworm to install mmsd-tng

Interesting... I added "non-free-firmway" to  /etc/apt/sources.list and  /etc/apt/sources.list.d/mobian.list, but "apt update" still fails with the same error. Zebulon Walton, the thread you linked had a lot of ideas, but they eventually converged on running " apt-get dist-upgrade" first. I did that, and it succeeded, however, running apt upgrade afteward still failed. That seems really strange to me, that the more rigorous update would succeed whereas the lighter one failed.

if you get same error, then probably keys are still missing.

Code:

curl -s https://repo.mobian.org/mobian.gpg | sudo tee /etc/apt/trusted.gpg.d/mobian.gpg
# or
wget -O - https://repo.mobian.org/mobian.gpg |  sudo tee /etc/apt/trusted.gpg.d/mobian.gpg

other hand, you could manually download https://repo.mobian.org/mobian.gpg file and copy it to /etc/apt/trusted.gpg.d/mobian.gpg . root or sudo is required.

i have a bad feeling that updating packages afterwards may be complicated, so i suggest aptitude.
