Hello,

I have an error when i run this command :MQ_ARCHIVE=IBM_MQ_9.0.0.0_LINUX_X86-64_TRIAL.tar.gz make build-advancedserver

The output is :

• false
• DIR_EXTRACT=/tmp/mq
• mkdir -p /tmp/mq
• cd /tmp/mq
• curl -LO http://build:80/IBM_MQ_9.0.0.0_LINUX_X86-64_TRIAL.tar.gz

The command '/bin/sh -c chmod u+x /usr/local/bin/install-mq.sh && sleep 1 && install-mq.sh' returned a non-zero code: 2

Thanks for your help.

Outside the container i can execute tar -zxvf ./IBM_MQ_9.0.0.0_LINUX_X86-64_TRIAL.tar.gz successfully inside downloads directory. So i suspect that the curl -LO http://build:80/IBM_MQ_9.0.0.0_LINUX_X86-64_TRIAL.tar.gz do not download the entire file.

Thanks for your help.

I have the exact same issue. Looks like the issue is with the temporarily created network and/or the web server that's supposed to host the tar.gz.

Thanks for your response.

Any workaround for this issue ?

Hi @faissalwise,

When we see the error gzip: stdin: not in gzip format it means that the curl command has failed to download the archive file from the temporary nginx http server we have started. The most common cause of this is that the archive file in the downloads directory does not have world read permissions on it so the curl command cannot download it. Please check that the permissions for this archive file allow anyone to read it.

On a side note, if i remember correctly the 9 LTS archive you are using does not contain debian installation files but instead contains rpm install files. This will be a problem later on when the install script attempts to install MQ as it will try and do it using apt install which will not work with rpm install files. A possible workaround would be to change the base image from ubuntu:16.04 to centos:latest which will cause the install scripts to use rpm to install instead.

Hi @parrobe ,
It's resolved,my problem was the proxy in the curl command,so i use curl with noproxy option and that works.

Thanks.

What you have done in local to resolve this issue ?
Other than changing the base image from ubuntu:16.04 to centos:latest
I am having the same issue still

Can you please clarify the name of the tar.gz file you are using, and that you've checked it's downloaded correctly (is really a valid file)?
