unexpected jamf version string: %q

Error message

unexpected jamf version string: %q

What it means

getJamfBinaryVersion parses the output of 'jamf version' (e.g. 'version=10.46.1-t1683911857'); this error fires when the trimmed output does not match the expected 'version=...' pattern, so the version cannot be extracted. A missing jamf binary is handled separately and is not an error.

Solutions

1. Check the jamf binary version output manually (/usr/local/bin/jamf version) to see its actual format
2. Upgrade jamf to a version with the standard output format
3. Report the unexpected format to Teleport if jamf changed its output
