influxdb failed to install

[lmackay@ed.ac.uk]

Hi all,
sorry if this has already been discussed.
I have been trying to get influxdb to install for a couple of days and have reached a dead end.  
The install failed the first time, and now when I uninstall and reinstall its loading from a cache.  

It shows as installed in apps, but dead in processes and cant be restarted. 
Kapacitor and chronograf appear to be running ok. 

Is there something I can do to force SignalK to download fresh?  Would this help?  

Any help would be amazing.
cheers
Logan
