Unable to update pi-star operating system

[IV3BVK]

Hi everyone,
for a few months I have tried to update my various pistar hotspots, but from the error reported below this is no longer possible.

Probably the repositories of this Debian version are no longer available !!

Is there a platform update planned, with the use of a still active Debian version?
Otherwise this distribution will soon become unusable!

Waiting to receive a certain answer to this question, I wish you the best QSOs!

Take a look at this: <viewtopic.php?p=23456&hilit=public+keys#p23456>

Are there any plans to update that operating system?
It would be a real pity if the development of Pi-Star ends.
(I am unfortunately not a developer, otherwise I would be happy to offer my help).

I am already aware of Andy's announcement...
but unfortunately it does not answer my question,
but only suggests that there will be no further development?

It requires people with the necessary skills to step forward and do the needed work.

You're not a developer, and neither am I.

Perhaps there are people with the needed skills who will step forward? I don't know.
