apt-get upgrade fails

Hello, On my ubuntu 20.04 I can no longer update syncthing:

Err:1 https://syncthing.ams3.digitaloceanspaces.com syncthing/release amd64 syncthing amd64 1.23.6 Could not handshake: Error in the pull function. E: Failed to fetch https://syncthing.ams3.digitaloceanspaces.com/dists/syncthing/release/binary-amd64/syncthing_1.23.6_amd64.deb Could not handshake: Error in the pull function.

Please advise.

Maybe you’re missing some certificates or have an unhappy firewall or proxy?

My corporate firewall was killing me. Thank you very much for your help!

You are probably struck by a Firewall SSL MITM proxy. You need to add the proxy certificate to the certificate story of your os. But adding trusted domain names to the proxy can be an administrative burden (and depends if you or IT can and will do it). Glad you fixed it.
