just in case someone is running a Linux distribution that is not officially supported by CERNbox with its own client package. (I had this problem with Ubuntu 19.10, which got a CERNbox package only very recently)
It is possible to use the stock owncloud client, but only if you create a ‘custom’ config setup:
In my case, I downloaded the owncloud-client version 2.6.0 from www.owncloud.org.
Provide this URL for the server together with your CERN login: https://cernbox.cern.ch/cernbox/desktop
Then instead of choosing “sync all” in the setup wizard, I choose “individual sync connection” (or something sounding very similar ;). This allows you to only select the ‘/home’ root folder which is the one with your personal files.
When trying the slightly older owncloud-client V 2.5.1 (which is shipped by default with Ubuntu 19.10) it did not work. Its setup wizard tried to access the ‘/eos’ root folder as well which threw an error because of missing access permissions and would not let me finish the setup procedure.
I’ve been running the stock owncloud-client V 2.6.0 now since late November without any issues.
In the beginning, it showed a scary warning that the CERNbox owncloud sever would be too old in relation to my client version.
That, however, did not matter as I was reassured in a CERN IT ticket. The warning is now gone, I guess the CERNBox server version of owncloud might have been updated.
I’ve tried to find out which owncloud-client versions are meant to be compabitble with which owncloud-server versions by wading through their release notes but did not succeed…
Hope this is info usefull for someone,
