Updated from 2 -> 3.1 - Local Map Not Working

FlightAware ADS-B Flight Tracking
1

I just updated to 3.1 from 2.1, and cleaned up and bunch of stuff, removed mutability, etc. to get as close to a clean install as possible without starting over. Everything is working fine (feeder is feeding, piaware-status is all fine), but when I navigate to the local site to try and view the map. A few things happen:

  1. When I goto 192.168.1.X:8080 in Chrome, a map loads, but I get the following error message:

Problem fetching data from dump1090.
AJAX call failed (error). Maybe dump1090 is no longer running? The displayed map data will be out of date.

  1. When I goto 192.168.1.X:8080 in another browser, the page won’t even load

After doing some research, it sounds like I could have an issue with lighttpd? I ran sudo systemctl status lighttpd and got the following output:


pi@raspberrypi:~ $ sudo systemctl status lighttpd

What do I need to do to fix this issue?

Oh and the content of lighttpd.conf is:


server.modules = (
        "mod_access",
        "mod_alias",
        "mod_compress",
        "mod_redirect",
#       "mod_rewrite",
)

server.document-root        = "/var/www/html"
server.upload-dirs          = ( "/var/cache/lighttpd/uploads" )
server.errorlog             = "/var/log/lighttpd/error.log"
server.pid-file             = "/var/run/lighttpd.pid"
server.username             = "www-data"
server.groupname            = "www-data"
server.port                 = 80


index-file.names            = ( "index.php", "index.html", "index.lighttpd.html" )
url.access-deny             = ( "~", ".inc" )
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )

compress.cache-dir          = "/var/cache/lighttpd/compress/"
compress.filetype           = ( "application/javascript", "text/css", "text/html", "text/plain" )

So I tried removing piaware, dump1090-fa, and lighttpd, restarting, and then reinstalling. However when reinstalling dump1090-fa I got the following error message and I’m back to the original issue:

I’m not super tech savvy but it seems like /etc/lighttpd/conf-enabled/89-dump1090.conf is missing? When I try to open it with nano, nothing exists?

OK so it seems like this might be an issue with having mutability previously installed. It’s trying to use 89-dump1090.conf which is what mutability uses, but the Piaware setup uses 89-dump1090-fa.conf

I can’t figure out where I need to update the correct file to point to though. I looked in /etc/lighttpd/lighttpd.conf but don’t seem to find anything.

I futzed around and lighttpd is running now, but when reinstalling dump1090-fa I get the following error:


Enabling lighttpd integration..

I think this is that dump1090-mutability is not disabling its lighttpd configuration when the package is entirely removed (purged), so part of your lighttpd config now points to a nonexistent file.

Try removing /etc/lighttpd/conf.enabled/89-dump1090.conf (if it is there, it’ll be a symlink pointing to a nonexistent file)

Also, if you’ve been messing around with config files be aware that reinstalling a package doesn’t restore deleted conffiles. You probably want to purge-and-reinstall at this point:



apt- get remove --purge lighttpd dump1090-fa
apt- get install dump1090-fa

(remove the obvious space used to work around mod_security)

Huzzah, thanks for the help, that worked. You were exactly right re: messing around with the conf files, and reinstalling doesn’t restore. The purge did the trick.
