** Description changed:
+ [Impact]
+ This bug has minimal impact to users. Warnings are being thrown by the
service in its journal; but that seems to be the only issue -- valid results
are still being returned by the prometheus collector in the number of packages
that need updates for each repository; along with node_reboot_required.
+
+ The bug fix is to clean up the regex to avoid the warnings.
+
+ [Test Plan]
+ 1) Run /usr/share/prometheus-node-exporter-collectors/apt.sh
+ 2) Validate that it returns without awk warnings.
+
+ [Where problems could occur]
+ - An invalid regex might cause repository stats to be returned in the wrong
format for parsing by prometheus.
+ - Invalid regex would still show warnings or errors in awk.
+
+ ---
+
Every time the prometheus-node-exporter-apt.service service runs; it
comes out with awk warnings; the regex used is understood but misparsed:
