Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
python-dev : Depends: libpython-dev (= 2.7.15~rc1-1) but it is not going to be installed
Depends: python2.7-dev (>= 2.7.15~rc1-1~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
And this problem maybe relevant to the source.list file
The sources.list_default and source.list are both empty in the Xavier and the host.
The the folder in host is " ~/nvidia/nvidia_sdk/DRIVE_Software_10.0_Linux_OS_DDPX/DRIVEOS/drive-t186ref-linux/targetfs_ a /etc/apt/sources.list"
Should I re-download and re-flash the Xavier to solve the problem?
We will check this. Before any finding, please use below as the content of source.list on your target as a workaround. Thanks!
