Error when installing Sametime Premium 12.0.1 on Centos 7

I'm getting the following error when I try to install Sametime Premium 12.0.1 on Centos 7.9.

Pulling community (hclcr.io/st/chat-server:20221110-2253)...
ERROR: unauthorized: unauthorized to access repository: st/chat-server, action: pull: unauthorized to access repository: st/chat-server, action: pull

Any ideas what could be the cause?

First thought is to make sure you ar running as root or SUDO with appropriate priveleges.


Second thought - any permissions issues in the folder you are extracted to?

Yes I'm running as root and I'm having read and write access to the folder.

What version of docker/docker-compose is installed?

Is Docker running?

Past that - I think a case will be faster so that we can maybe get a look at your system.

Thank you Anthony.
Yes it's running, I will open a case.

Thanks - Did you confirm 'docker-compose' is working well? Issue a 'docker-compose version' command and tell me the output

Yes it seems to be.

docker-compose version 1.29.1, build c34c88b2

Ok - good - we seem to have eliminated the most common issues.

Lets look at the size (and permissions) of the tar file that was extracted from the zip.

-rw-r--r--. 1 root root 28508160 Nov 10 18:24 sametime_premium.tar

There's our issue - it should be much larger - either the zip was not downloaded fully or the unzip failed?


How is your diskspace?

FTR - this is the size I have in my reference copy -


-rw-r--r--. 1 root root 2661848879 Nov 10 18:24 sametime_premium.tar

and the zip itself should be - 2647285929

That was the problem.

I checked the Zip's MD5 hash before uploading to the server but not after.

The size looked fine but the hash on the server didn't match.

After uploading the file once again the install worked.

Thank you very much for your help!

Fantastic!
