Earlier quoted context omitted.
I wish, but the signature is actually compiled into the snapd (the software on your system)'s binary. Deliberately impossible to reconfigure. Like I said, you can change the signature... by distributing a forked binary to users that would be incompatible with the main store.
Isn't this good? I mean if you are a distribution you compile the software yourself so you can add the distribution keys (there are some that don't compile stuff ). Probably you are thinking there should be atext file in your home where you could add new signature to be sued, but that could be a security issue so probably needs to be something more safe,did any serious patch was sent to improve this and was it reject…
I knew things were bad around Snap, but I didn't think they were attacking their feet with such fire power.
