Hi there Eric and others I tried to install the JBrowse tool on a dev branch server running on an Ubuntu 14.04 VM. It got stuck at the package_gnu_coreutils_8_22 dependency (revision ac64dfe4b1fb) - this ended up in "Installing tool dependencies" state. If I go look at the tool details it highlights errors in package_perl_5_18 which in turn refers to errors in gnu_coreutils (just "Error" state) and then this more informative failure for perl: "tar (child): local-lib-1.008009.tar.gz: Cannot open: No such file or directory tar (child): Error is not recoverable: exiting now tar: Child returned status 2 tar: Error is not recoverable: exiting now" I wonder if this is a sign of a download error? Digging a bit more I find the error "Shutting down process id 21094 because it generated no output for the defined timeout period of 3600.0 seconds." for gnu_coreutils. I'm trying to do a reinstall of the gnu_coreutils and perl packages to see if I can get further. Peter
