    But then the fr24-directories also are owned by the user dump1090. I don't think it is neccessary for fr24feed to change the permissions of /run/dump1090-mutability; maybe only in case if there is no dedicated dump1090-mutability package installed.

    And going by my tests I think thats exactly what its based on.

    If you look for the USB claim error you will find it's due to being in-use already by dump1090.

    Needs restart and checking how you start it (auto/manual)

    You will need to use commandline to find out why or edit the config file.

    Assuming you are on a RPi, some of the commands are outlined.. https://forum.flightradar24.com/thre...ll=1#post74851

    you can also edit
    sudo nano /etc/fr24feed.ini
    OK - issue was fr24feed was not starting. Sudo fr24feed start got it going. And changes in fr24feed.ini are reflected in <ip_of_pi>:8754/settings.html.

    I now need to manually start the fr24feed each time. So how do I fix this ??

    From the various posts - I've tried sudo service fr24feed start ( and rebooted) and also sudo systemctl restart fr24feed.

    You mentioned editing the config file. Whats it called ? so I can have a look at it.

    Thanks

    Config file is for fixing bad settings, doesn't effect the start/stop.

    But from what most are experiencing there is some changes to permissions of files related to said run files.

    It's getting too tricky to fix them all so suggesting reimage and start fresh now.

    But the adjust to permissions a few posts back may help you too. Big unknowns

    fr24feed broken (Raspberry Pi)

    As a newby I'm not sure if this is the right topic to post.

    However I tried to update my old Raspberry Pi and notice there was a new fr24feed.
    But for some reason it's not going .. tried to remove and reinstall but get:

    root@debian512pi:~# apt-get install fr24feed
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    fr24feed is already the newest version.
    0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
    1 not fully installed or removed.
    After this operation, 0 B of additional disk space will be used.
    Do you want to continue [Y/n]? y
    Setting up fr24feed (1.0.19-5) ...
    /var/lib/dpkg/info/fr24feed.postinst: 35: /var/lib/dpkg/info/fr24feed.postinst: systemctl: not found
    /var/lib/dpkg/info/fr24feed.postinst: 47: /var/lib/dpkg/info/fr24feed.postinst: systemctl: not found
    dpkg: error processing fr24feed (--configure):
    subprocess installed post-installation script returned error exit status 127
    Errors were encountered while processing:
    fr24feed
    E: Sub-process /usr/bin/dpkg returned an error code (1)

    Still use the old version -> PRETTY_NAME="Raspbian GNU/Linux 7 (wheezy)"
    The apt sources.list contains -> deb <link> flightradar24 raspberrypi-stable
    Seems I cannot mention any links ....

    Any help how to solve this would be welcome.
    It only goes about the fr24feed, I use the original dump1090.

    Thanks,
    Matthijs

    Because you didn't use SUDO

    But it is already latest.

    Why should I use sudo when I am root?
