error when installing plugins

[McDermott, AS Amanda (5841) @ IS]

When trying to get plugins automatically from Nessus, I attempted the
./nessus-update-plugins command and got the following error:
 
# ./nessus-update-plugins
Something went wrong when installing the plugins - uncompressing the plugins
arechive failed
 
 
Can someone tell me why I keep getting this error?
 
Thanks,
