Upgrade to 15.3 failed. rick.watts  2015-11-23 17:18
Status: Closed
I'm attempting to upgrade to 15.3 on Windows. The installer gives me the following message: Postgres upgrade failed: 1. Unable to recover. However before that a message flashed up complaining about invalid characters in the install path. The message did not persist long enough for me to read it all :(

Now it would appear that my install is broken and I have no idea how to fix it without reverting to a backup.

Hi Rick,

It sounds like you hit this issue:


We have a fix that is being tested right now. The good news is that with the patched installer the recovery should be very easy.

Hi Rick,

Hi Rick,

We've posted an updated installer that fixes this issue:


Prior to running the updated installer, please move the "upgrade_backup" file that the previous upgrade attempt created to a different location. It should be in the root of the install directory - typically "C:\Program Files\LabKey Server" or similar. If it's still in the same place when the installer starts, you'll get a different error message and will need to rerun the installer a second time.

Thanks Josh,

We're running Labkey on a virtual machine and just rolled back to a previous snapshot so we should be good to go.
