I have flashed the Jetpack 3.1 on the TX2 and want to install the DJI Onboard SDK on it.
Therefore I needed to install cmake. But if I want to install it with:
sudo apt-get install cmake
It sais:
Package cmake is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package ‘cmake’ has no installation candidate
It seems like apt-get is not working for other basic programms like nano as well.
Hi, I already did that, I also added another repository, but it didn’t work. Is it possible, that something at the Jetpack installation didn’t work well?
I have package cmake installed (R28.1), but I also have extra repositories enabled. Not sure if you just need more repos enabled (see “/etc/apt/sources.list”).
This is how I do it. Just do an “sudo apt update” after a change.
FYI, if “sudo” itself fails (if permission to sudo is denied), there may have been an error in the “apply_binaries.sh” step of a flash causing incorrect permissions. This would be serious enough you would have to flash again. Not related to packages not found, but worth mentioning because on rare occasion some people have hit issues with sudo (versus what sudo runs as its argument).
