Unable to update from 2.6.0 to 2.6.2

Hi @mohamedhm, thanks for reaching out. I'm sorry to hear you're having problems updating.

I've reviewed the logs you provided, and I can see that there is a third-party software source installed on the device and that it doesn't appear to be responding correctly:

E: The repository 'https://packagecloud.io/ookla/speedtest-cli/raspbian bullseye Release' does not have a Release file.

This problem could be a transient fault with the third-party software source, so it may start working again after a few hours or days. Unfortunately, if it doesn't, or if you need to upgrade sooner, you'll need to remove the third-party software source using the provider's instructions.
