I installed Freedombox by this way: [debian wiki]/FreedomBox/Hardware/Debian
using Raspbian Buster Lite.
All is alright, but today I tried to install Coquelicot and I get this error:
Error during installation W: GPG error: Index of /debian buster-backports InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 04EE7237B7D453EC NO_PUBKEY 648ACFD622F3D138 E: The repository ‘Index of /debian buster-backports InRelease’ is not signed.
Wow I’m dumb. I’ve been trying to change to backports for 10 minuets now just copying and pasting the link. I’ve been copying the number of visits to the website this whole time. For anyone is clueless as me, do not copy the number sounded by spaces after the domain name.
no need to use ubuntu keyservers though
probably keyring.debian.org, would be more adequate. Given you ca assume freedombox users would probably prefer to rely on the debian key reviewed keys. Instead of keyserver.ubuntu.com that is.
