I don't think https://mirrors.switch.ca is a repository that is there by default. Presumably you have changed this on your OctoPi image?

On a fresh OctoPi 0.18 /etc/apt/sources.list looks like this:

deb http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi

Double check what yours has.

Other mirrors are an option, and can be faster than the raspberrypi.org one for wherever you are located in the world. But I wouldn't change it to something that doesn't work...

According to https://www.raspbian.org/RaspbianMirrors it's a valid mirror, but it doesn't seem to be updated. A quick google pointed me to this; https://dev.to/ryderdamen/fixing-broken-mirrors-raspberry-pi-1een seems like it might be a common problem with that mirror, but that site has a fix.

Thanks GordonTGopher and Charlie_Powell that fixed it.

Added “http://muug.ca/mirror/raspian/raspian buster main contrib non-free rpi” to the top of the /etc/apt/sources.list file via “sudo nano /etc/apt/sources.list”

I did have “Cache entry deserialization failed, entry ignored” come up twice under “installing build dependencies” and twice under “Updating pip”

It otherwise appears to have completed the migration.
The main webpage comes up without error.

I guess I’ll have to print something later to be sure.

Thanks for your time and help.
Bobby
