No webserver after power outage

[themaninspain]

My OSPi suffered a power outage today. After reconnecting power I can no longer access the OpenSprinkler web page. I get a connection refused message.

Looking at the list of ports with netstat there is no process listening on port 8080

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:ssh 0.0.0.0:* LISTEN

running /etc/init.d/OpenSprinkler.sh status gives me this:

`sudo /etc/init.d/OpenSprinkler.sh status

I’ve trawled through all of the log files and cannot see any error messages.

The OSPi is a month old and I am using a RPi 2 with Raspbian Buster.

Any suggestions on how I can fix this?

An update:

I’ve tried a fresh install on a different RPi (Raspbian Lite) and I have the same problem!
The WebUI is not available and nothing is listening on port 8080.
So it seems this is not an issue with my OpenSprinkler/RPi

PS: Is there any way to change the post title to reflect that this is really a non-functioning WebUI and not an issue with a power outage?

OK, I’ve solved the problem.

When I did the fresh install I immediately updated all of the packages before building OSPi.
It turns out that there is a package (not yet identified) that interferes with the web UI.
I did a fresh install of Raspbian, no updates and then built ospi and it now works.

My mistake was that I had enabled unattended upgrades on my opensprinkler Pi and when it rebooted after the power outage the updates kicked in and I no longer had a working web UI.

Now all I have to do is find out which package is causing this.

I’ve now identified the errant package, it’s raspberrypi-kernel
