[galaxy-dev] Internal Server Error during installation of ncbi_blast_plus

Hi guys, we are currently estalishing our own local Galaxy instance. However, when we try to install "Repository 'ncbi_blast_plus'" from the Galaxy main tool shed via the admin pages, we obtain the following error "Internal Server Error Galaxy was unable to sucessfully complete your request An error occurred. This may be an intermittent problem due to load or other unpredictable factors, reloading the page may address the problem. The error has been logged to our team." We tried to install on three different days. Hence, we believe there might be another problem. Thanks for any help. Best regards, Jens
