DUET3 MB6HC with SBC - "File has unexpected size"

[Impalanator]

Hi all,
I am trying to upgrade my 6HC with a raspberry pi from 3.5.0-rc.2 to 3.5.2 by using apt-get commands and I am getting the following:

Get:1 https://pkg.duet3d.com unstable/armv7 armhf duetwebcontrol all 3.5.2 [9,515 kB]

Any idea on this one?

Thanks,

Cancel this one, I was on Buster and not Bookworm. I followed this:
https://docs.duet3d.com/en/How_to_guides/SBC_Buster_to_Bookworm

And now it is working fine on 3.5.2.

Thanks,
Ed
