Cause

The installer tool extracts some required files into the system temporary directory (which by default is set to /tmp on a Linux machine). The tool attempts to execute actions in that temporary directory. If the temporary directory does not have executable rights for the user in question, or if the directory is on a volume that is mounted without an exec option, it will fail.

The operating user may not have permission to execute files in the temporary directory for one of the following reasons:

The noexec flag is present on the temporary directory.
If SELinux is enabled, it is configured by default to block executables from running in the temporary directory.

This error can also appear if there is not sufficient space in the system temporary directory partition where the files from the installer are extracted.

Action

On Linux, allow execution rights on the system temporary directory by running chmod +x <PATH TO DIRECTORY>.
Increase the allocated disk space for the system temporary directory.

SELinux

Work with a System Administrator to modify SELinux permissions to allow executables to be run in the temporary directory.

Noexec Flag

Temporarily remove this flag by executing the following command: mount -o remount,exec /tmp

Set it back by executing the following command: mount -o remount,noexec /tmp

Affected Versions

This article applies to all versions of Appian running on the Linux operating system.
