Plex Media Scanner return nothin

Hello,

since last update my auto refresh script won't work.

root@ubuntu:/usr/lib/plexmediaserver
#> ./Plex\ Media\ Scanner -l
./Plex Media Scanner: error while loading shared libraries: libminizip.so.1: cannot open shared object file: No such file or directory

so I set the variable LD_LIBRARY_PATH

root@ubuntu:/usr/lib/plexmediaserver
#> export LD_LIBRARY_PATH=/usr/lib/plexmediaserver

And retry

root@ubuntu:/usr/lib/plexmediaserver
#> ./Plex\ Media\ Scanner -l
root@ubuntu:/usr/lib/plexmediaserver

Nothing happens ... :(

What can I do ?
