Updating and uninstalling not working

[cschwem2er]

Hi,

I just tried to update all my anaconda packages with conda update --all and received an error for nbpresent:

Uninstalling the package was also not working:

My user account is the owner of the corresponding packages and thus has read and write permissions. Can you help me out here?

It does not seem you have writing permission on home/cs/anaconda3/etc, am I right? If you can't change that thing, I guess you will have to perform a "manual" installation and write the config files in the "user" space. Pinging @bollwyvl, so he can give you his advice as well...

[bollwyvl]

@methodds Yep, hooray permissions!

Perhaps some part of your install was run by a different user? This could potentially be problematic!

ls -lathr /home/cs/anaconda3

If you're seeing anything other than cs as the owner, then you probably just want to:

chown -R cs /home/cs/anaconda3

... unless this is a shared install between cs and other users...

Resorting to a "manual" install is a bit nasty, and would likely run into the same issues as the conda-managed approaches... and is fraught with more peril (though your jupyter should always still work). But anyhoo:

jupyter nbextension install nbpresent --user --py
jupyter nbextension enable nbpresent --user --py
jupyter serverextension enable nbpresent --user --py

Of note, though, is that doing this may will mess with your other extensions, as presently serverextensions from your conda env will be clobbered by your user dir config... but not your nbextensions, which can lead to some "interesting" effects.

Let us know how we can be of additional assistance!
