Cant Update and Console wont run

I have been trying fix may system as it wont update anymore, and i cant use Browsers with the sandbox

I guess its unfixable …I remeber seeing in the Console that you could erase he disk and install CLDX18 from an ISO …so was going to try that but keep getting and ERRNO 111 I had this problem before and i needed to run

 # /etc/init.d/calculate-core start

before console would run …this time i get

calculate /home/guest # /etc/init.d/calculate-core start
calculate-core    | * Start calculate core ...
calculate-core    | * Calculate core is not configured!
calculate-core    | * ERROR: calculate-core failed to start

any way to sort this issue out
Thank you
