Error installing Volt Iris upgrade

Volt Iris uses git to install fix packs, running git commands as a specific user. This will fail if you have gpg signing enabled.

Symptoms

If this is the cause, you should expect to see:

  1. The install fails during the “Executing pre install phase” phase.
  2. Looking at the iris_installer_failure.log file you’re directed towards, you should see reference to gpg signing failing:
    [stderr] error: cannot run gpg: No such file or directory
error: gpg failed to sign the data
fatal: failed to write commit object
  3. Looking at your global .gitconfig file, in your user directory, you will see a [commit] section with gpgsign = true

The process inherits the git config from your global .gitconfig file in your user directory. You will need to temporarily turn off gpg signing in that config.

  1. Set gpgsign = false and save your .gitconfig.
  2. Run the installer again.
  3. Reset your .config back to gpgsign = true.

This was identified in Volt Iris 9.5.53. In About Iris, this shows as Version 9 Service Pack 5 Fix Pack 53 (2025.04). This may be addressed in future versions.
