Calibre install errors chown: cannot access /home/calibre

Newbie here, thought that I would try openmediavault on a amd 6 core cpu with 8gb ram 4 x 4tb raid 5, 2 x 3TB mirror, 1TB root, new to Linux so I have installed omv without errors, setup 2raids, omv-extras.org with the plex plug (works great), use Putty to control with http site, trying to install calibre but having an issues and not sure if it is something that I have done or what. This is the error message when installing the plugin

Looks like a permissions issue for /home/? Tried to uninstall and reinstall but no luck. Have been doing a lot of reading on various calibre forums and sites but nothing has helped . appreciate any help.

Hey thank you for your help here, I followed the above without errors, it updated the local files, and file permissions purged internal cache, restarted engine daemon then it created index of packages, index openmedia plugins . checked the plugin on gui entered folder locations and still have

Sorry , not sure if I require to reboot or something else. Lots to learn. thank you for your patients.

Yes that is the error message after inserting the settings that include , enable, data directory,user, password, shared folder, then I click import, the error message comes up, clicked on ok, then a box comes up says importing, stop is greyed out but close there, nothing happens. Should I try to uninstall?

Yes of course, oh crap. Its starting the import now. My inexperience was showing , I really appreciate your help here.
