apt update error: debian buster suite changed to oldstable

[meonkeys]

sudo apt update from a shell on the latest picroft emits an error about a repository:

Get:1 http://archive.raspberrypi.org/debian buster InRelease [32.6 kB]

Environment (please complete the following information):

• Device type: Raspberry Pi 3B
• OS: Picroft
• Mycroft-core version: 21.2.2
• Other versions: Jabra 410 USB speaker+mic

Workaround
This seems to work. Running it once clears the error from happening on future executions of sudo apt update. I'm not clear on exactly what it does, though.

sudo apt update --allow-releaseinfo-change

Thanks for this - I'm sure others will be hitting the same issue.

Because we don't manage updates to Picroft like we do the Mark II I'm not sure there's much we can do beyond updating the downloadable Picroft image.
