Error encountered: An unknown error occurred while access the upgrade file.

Hi all,

I was upgrading my call manager subscriber server from 7.1.3.10000-11 build to 8.0.2.41006-1 build, got the following error and the upgrade failed,

Status: Error encountered: An unknown error occurred while access the upgrade file.

While the same upgrade was successful on the pub.

Need help.

Hi

You mean the same downloaded file? Or the same exact CD?

Aaron,

Its the same downloaded file.

I found that when upgrading from a remote machine I had to point to a directory with only the upgrade file in it. Prior to that I got the same error.

Brad,

I've seen that a number of times with 7x upgrade files.  I would like to say it's consistent but it hasn't always been.  I've done a number of upgrades and sometimes I would run across that issue and other times, I would not (there would be multiple files in the SFTP path).  After a few times, I just started always putting my upgrade file in a dedicated folder.

Good catch...and you're not alone in experiencing it.

I faced same error while upgrading 7.0.2 to 7.1.3-20000-2 and after failing few times here is what i tried

1. add a ntp server to server ( even though the NTP was not really reachable ..just add one on server before you start upgrade)

2. try placing only one file on sftp root directory..

This is still happening in 11

This is still happening in 11.x upgrade attempts, put OS in permissive mode and make sure there is only one file the directory path.  Random results with this one.
