Cause

The two known reasons for this issue are as follows:

1. There was a problem with the way that the Appian installer file was copied to the Linux host server.
2. There is no space left in the /usr/tmp/ directory at the time of the attempted Appian installation.

Action

Perform the following actions depending on the determined cause above:

1. Re-copy the installer file as a user with the right permissions on the Linux host server and test again.
2. Ensure there is enough free space in the /usr/tmp directory.
