Unsuccessful using danielt's unofficial Debian installer on the PBP

[joeDoe]

I'm trying to install Debian to the eMMC on my Pinebook Pro using Daniel Thompson's unofficial installation script. 

When ">>>> Checking for updates" (right after ">>>> Mount special file systems")

I get the error

Code:

Err:1 http://deb.debian.org/debian bullseye InRelease
  Unknown error executing apt-key

which is repeated for updates and security updates.  A few lines later, amongst warnings

Code:

E: The repository 'http://deb.debian.org/debian bullseye-updates InRelease' is not signed.

which is repeated for the others.

Other Debian machines on the LAN can update just fine.

This first occured last night, and I just left it thinking is was a temporary problem with the repository.  But, it has happened 3 more times today.  I don't understand what I am doing incorrectly.

Can anyone suggest what I need to do to get beyond this?

I think it possible my installer has outlived it's usefulness (although I'm still happy to accept patches to fix it for people who do still use it).

With the newer versions of u-boot that are starting to appear (tow-boot in particular) it is now possible to install Debian into a Pinebook Pro using the real Debian installer ISOs. I always intended to discontinue my installer once the firmware and mainline kernel had matured enough to allow real installers to work... in fact I was surprised it was needed for such a long time.

Hi Daniel,

I installed Debian on my PBP using your installer around the time of it's introduction. I have been very happy with the installation ever since, but I now see that your update repository is no longer available. Do you have any suggestions as to how I can perform kernel updates going forward without breaking my installation or having to re-install Debian ?

Rest regards,
Nigel.
