Repository signature verification failure.

I have yet to solve this problem when doing an apt-update. How do I fix this? I have no keys in /etc/apt/trusted.gpg.d and I have a symlink /etc/apt/keyrings pointing at /usr/share/keyrings. Spent almost two hours with no solution. Help please?

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. OpenPGP signature verification failed: https://repos.rcn-ee.com/debian trixie InRelease: Sub-process /usr/bin/sqv returned an error code (1), error message is: Signing key on A72AB0B90B8685C91777A377D284E608A4C46402 is not bound: No binding signature at time 2025-09-19T17:34:16Z because: Policy rejected non-revocation signature (PositiveCertification) requiring second pre-image resistance because: SHA1 is not considered secure since 2026-02-01T00:00:00Z

You’ll find an updated apt sources files here on the file system:

voodoo@21-am335x-bbb:~$ ls -l /etc/bbb.io/templates/apt/beagle.*
-rw-r--r-- 1 root root 279 Jul  3  2025 /etc/bbb.io/templates/apt/beagle.list
-rw-r--r-- 1 root root 159 Jul  3  2025 /etc/bbb.io/templates/apt/beagle.sources

Copy the version you want to use under:

/etc/apt/sources.list.d/

and remove the old one saved in /etc/apt/sources.list
