How to solve Preparation failed error during service update

(1) ShareShare
ReportReport
Posted on by Saran S 333
Hi community,
 
When I try to apply a service update on my Dev environment, I receive a /Preparation failed/ error, and the log is also empty.
I attempted the update using the LCS admin login.
My C drive has 40GB of free space, and my K drive has over 200GB of free space, but I still encounter the error.
Does anyone have a solution for this issue?

    My usual checklist would be something like:
     
    Check admin account is still default in LCS
    Check diskspace: already done
    Check everything closed, e.g. visual studio
    Restart box and retry
    Make sure custom code on the box is in a build state - if not, build models and then restart (no sync needed)
    Finally the sledgehammer approach - provision a replacement

    Resolved.
     
    The SSL certificate had expired.
    After rotating the SSL certificate from LCS and performing the service update, it is now working.
