Deal all,
I aquiered a Jetson nano few weeks ago and I am in trouble to follow any tutorial because any time I have to install a new package I end up with the following error message. I am starting to think that I have an issue with my source.list file.
How can I be sure of the following things :
1-my source.list file is correctly configured
2-the package I want is available on the source I have configured
Package python3-numpy 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: Unable to locate package libpython3-dev
E: Package 'python3-numpy' has no installation candidat
Below example of issues I had but I found out on Ubuntu – Package Search Results -- bionic that they existe for my linux distribution :
-
python3-numpy
Ubuntu – Details of package python3-numpy in bionic -
hdf5-tools
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package hdf5-tools
But I found it : Ubuntu – Details of package hdf5-tools in bionic
