Running NEMS 1.5
Please wait for apt tasks to complete...
Done.
NEMS Linux is currently updating itself. Please wait...
There are no rolling upgrades to install.
"Important Exception: Due to the sudden and unexpected release of the Raspberry Pi 4 Model B 8 GB, NEMS Linux 1.5.2, while a point release, is in fact a major upgrade. Therefore, you will need to follow the Major Release Upgrade Instructions if you choose to deploy NEMS Linux 1.5.2. This is because the bootloader on the new board has changed from previous versions, so a rolling upgrade is not possible."
