I’m working on tegra B, I was trying to install opencv but I failed.
Then I just type the command : “sudo apt-get install locate” in order to locate a file, I got a message " No more space available in cache".

I decided to restart my TegraB, and now It’s full black screen! TegraA is working but no more screen on tegra B.

I already got this issue yesterday, I tried to install the desktop being on tegraA but it said it is already installed on Tegra B. So I decided to reflash… I lost a lot of time so I don’t want to redo this…

So please if anyone has an idea on how Can I solve this problem!!! Thank You very much!

Hi @nida.rahman1 ,

It’s not the" sudo apt-get update" the problem, the problem was the installation of opencv. It took all the cache memory… :o

Sorry that OpenCV isn’t officially supported in our releases. Maybe you can search if any way to clean Ubuntu cache.
