1. Running apt-get update broken

You may run into it while the apt-get update command is running during installation. The error is as follows:

[INFO] Sixfab user already exists, updating... [INFO] Updating sudoers... [INFO] Sudoers updated [INFO] Updating system package index... E: Repository 'http://raspbian.raspberrypi.org/raspbian buster InRelease' changed its 'Suite' value from 'stable' to 'oldstable' E: Repository 'http://raspbian.raspberrypi.org/raspbian buster InRelease' changed its 'Suite' value from 'stable' to 'oldstable' E: Repository 'http://raspbian.raspberrypi.org/raspbian buster InRelease' changed its 'Suite' value from 'stable' to 'oldstable' [ERROR] Installer faced an error during the following command, please re-run installer [ERROR] ***************************************************** [ERROR] sudo apt-get update -y [ERROR] *****************************************************

A simple fix for this is to either:

Run the following and manually answer 'y' when asked to confirm the relevant changes

❗️ Warning

This is NOT apt-get, but rather just standalone apt

sudo apt update

Run apt-get update with the --allow-releaseinfo-change flag to automatically confirm the changes for you:

sudo apt-get update --allow-releaseinfo-change

When I try to install CORE I get this error:

sudo apt update --fix-missing

3. Wwan0/Usb0 has IP address, but cannot ping through both of the network interfaces

If your cellular interface has an IP and connection is not available, the issue might be related to 'monthly limit'. To fix the issue, update the 'Fleet' to 'unlimited' from Asset details on Sixfab Connect.
