Cannot install components after flashing

Host PC’s OS : Ubuntu 16.04
Device(Tx2)'s OS : JetPack 4.2

I did many things to install components after OS flashing but I couldnt.

so I just tried install components by other way.

but I cant find cuda toolkit 10.0 aarch64 run file.

plz let me know how to get the file.

what if you reflash again and select components be installed at the time of installation from Jetpack installer?
are you getting any particular errors when trying to do post-install of the components?

I tried to reflash again and again but it didnt work
but i found install file and send it to jetson.
cuda toolkit was in cuda-repo file.
it works well. thx.
