Fresh install fails no pubkey for backports

Problem Description

I’m trying to do a fresh install on Pi4 but can’t because backports isn’t signed.

I suspect that backports is only there for phpmyadmin (which I don’t need), so how can I run the install without it?

For now, I added [trusted=yes] to the line in enable_backports.list but it’s not ideal

Environment

  • Hosted On? [name of hosting co]lan

I’ve not managed to find backports for Raspbian. I don’t think that you should be looking at a deb.debian.org repo.

I’m taking a look at this now, but you should be able to use the manual install progress in the mean time if it’s urgent: Installing Sympl - Sympl Wiki

It installed OK after I added [trusted=yes] to the backports entry, though it did show a warning message.
To be honest, I never checked to see if phpmyadmin works. But I suspect it will

I’ve pushed an update now, so all should be okay again.

The problem was due to checking for Buster in general, rather than specifically for Debian only, so a check for that means it’s now happy.
