Some security practicioners and practices require for the /tmp directory to be mounted as noexec. This prevents the execution of binary files stored in this directory in an attempt to mitigate malicious files being executed. However, this restriction can lead to issues with certain applications.

 

On some Linux systems, the following exception may occur when attempting to run the Neo4j Desktop AppImage:

A JavaScript error occurred in the main process
Uncaught Exception:
Error: /tmp/.org.chromium.Chromium.tZUuvB: failed to map segment from shared object

This is not a Neo4j Desktop exception but an issue with AppImageKit installed on the operative system, which requires exec permissions on /tmp. A workaround for this would be to set a TMPDIR environment variable inline:

TMPDIR=/home/yourusername/tmp ./neo4j-desktop-1.6.1-x86_64.AppImage
