To keep excellent customer experience with FastNetMon we use Sentry to report any failures from our installation tools implemented in Go.
Today we received following anonymised report about FastNetMon Community installation failure:
It was pretty clear that it caused by missing configuration policy flags for dpkg in our installer logic for old Debian 8 platform and we've added it.
We've added --force-confold and --force-confdef and released new version of installer app.
We did not receive any complaints about this issue from customer and it highlights importance of proactive failure tracking.
Next time it will work excellent and another or same customers will be happy about it.
