How to fix VAMI stuck on "Update installation in progress"

  If you ever get in a situation where an update of the vCenter Server Appliance is interrupted for any reason, you may get an error message “Update installation in progress” and find that you are unable to log in the VAMI.

I started the update from 7.0.1.00100 to 7.0.1.00300 and  have a problem with network interruptions

 I found KB67179 that describes the following procedure on how to fix it.

1. Make a copy of “/etc/applmgmt/appliance/software_update_.conf”_ you most likely won’t need it.                                                                                                                                                      cp /etc/applmgmt/appliance/software_update_state.conf /home/software_update_state.conf

2. Stop the applmgmt service which handles appliance configuration and provides public API endpoints for appliance lifecycle management.                                                                       service-control –stop applmgmt                                                                                          

   
   1 Remove the “software_update_state.conf” file
   
   rm /etc/applmgmt/appliance/software_update_state.conf
   
   
   Then start the applmgmt service back up.
   
   service-control –start applmgmt
   
   

1. Go back to the VAMI console and try to log back in, it should work now.

Note that when checking for update after logging back in I had to check for updates a few times before getting it back to normal. Then second time everything was fine were upgrade in successful
