Error during CA WA System Agent installation from CA WAAE DVD/ISO image: "/tmp/ Permission denied"

Workload Automation Agent


The CA Workload Automation System Agent installation fails on Linux system with the below error:

"/tmp/ Permission denied"


The error could be similar, if not exactly the same.

This would also stop the installation from progressing further.


The potential causes for this error are:

  • Inappropriate permissions set on /tmp 
  • /tmp partition mounted with noexec, which stops anything being executed under /tmp.


CA Workload Automation Agent 11.x and later, on Linux platform



  • Inappropriate permissions set on /tmp 

Check the permissions for the /tmp to confirm if execute permissions are allowed to the user.

If not, proceed to change the folder permissions accordingly.

drw-rw-rw- 10 root root 4096 Dec 2 02:47 tmp 

For instance, (as shown above) if /tmp doesn't have execute permission, try changing the permissions to provide execute (x) permissions to the user. 


  • /tmp partition mounted with the inappropriate permission

Check if the /tmp partition was mounted with incorrect settings.

mount | grep tmp

The above command will display if the /tmp was mounted with "noexec" settings. The "noexec" setting will stop any executable from installing from within the /tmp.

If this is confirmed, the settings can be changed and /tmp can be mounted with "exec" option for the installation.

You can run the below command (requires escalated privileges)

mount -o remount, exec /tmp


This will allow the installation to progress.

Additional Information


  • After install the change can be reverted as shown below:

mount -o remount,noexec /tmp
