Error updating/upgrading

Tutorials & Examples
1

Whenever I try to update/upgrade, either using apt-get or openhabian-config, I get the following error:

dpkg: error processing archive /var/cache/apt/archives/openhab2_2.2.0-1_all.deb (–unpack):
subprocess new pre-removal script returned error exit status 127

Any guidance? I’ve tried purging dpkg and getting a new package, to no avail

Hi @dpierron, Which version are you moving from and to?

What Linux system are you running on?

Hi @Benjy I’m running openhabian on a raspberry pi 2 and have openhab 2.1.0-1, wanting to update to 2.2.0-1

Status 127 usually indicates a command can’t be found. I’ve just tested an upgrade from 2.1.0-1 now and it was successful, let’s see if we can debug:

  1. Would you be confirm that /etc/apt/sources.list.d/openhab2.list contains:
deb https://dl.bintray.com/openhab/apt-repo2 stable main

  1. Could you post the contents of /var/lib/dpkg/info/openhab2.prerm (Remember to paste inside ```these marks```

  2. Could you post the full response of:

sudo dpkg --configure -a
sudo apt -f install
sudo apt install openhab2

@Benjy /etc/apt/sources.list.d does not contain openhab2.list. Seems problematic

Similarly, /var/lib/dpkg/info does not contain openhab2.prerm

@Benjy:

openhab2.list contains the correct content

/var/lib/dpkg/info/openhab2.prerm contains:

  remove|deconfigure|0)
    # 0 Indicates removal on an RPM system
    stopOpenHAB
    exit 0
    ;;
  failed-upgrade)
    ;;
esac

exit 0

Alright, it looks like the problem is in /etc/default/openhab2, the first line looks like it starts with -Dpython.home, which is invalid. Try commenting this line out for now.

If that doesn’t work, would you be able to show the contents of this file?

That fixed it, thank you very much!
