The following signatures were invalid: EXPKEYSIG 652CD31D2C8DF3D0 BSP:Generic OBS Project
The following signatures were invalid: EXPKEYSIG E15EAD0968576D90 BSP:IMX8 OBS Project
E: The repository ‘Index of /debian-security bullseye/updates Release’ does not have a Release file.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.

I fixed it in this way:

wget -nv https://repo.solid-build.xyz/debian/bullseye/bsp-any/Release.key -O Release.key
sudo apt-key add - < Release.key
sudo apt-get update
