Hi everyone,

I recently have installed a local instance of galaxy in my computer, everything worked fine until I changed the path for library_import_dir in the universe_wsgi.ini file, to upload files to data libraries.
I followed the Galaxy documentation to setup this feature:

This is the path in the universe_wsgi.ini file
library_import_dir = /media/New/Vladimir/My_RNA-seq/

The steps I followed are:
    Admin > Data Library > Create new data library > Add datasets > Upload directory of files
    file format was set to auto-detect
    server Directory was /media/New/Vladimir/My_RNA-seq/
    and we chose the option to link to files instead of copying them

When I try to upload files, galaxy displays the following error:

Error Traceback:
