Hi all, for those who want to flash their Jetsons from Ubuntu 22.04, this workaround still works. For Jetpack 5.0 just fill in information for Ubuntu 20.04 LTS.
Also while flashing, sdkmanager wants to install package python from apt which is not found.
14:00:23 ERROR: File System and OS - target_image: E: Package 'python' has no installation candidate
To workaround this:
sudo apt update && sudo apt install python2 equivs
equivs-control python
nano python
###
Package: python
Version: 2.7.0
###
equivs-build python
sudo apt install ./python_2.7.0_all.deb
sudo ln -s /usr/bin/python2 /usr/bin/python
