Ignoring file 'openhab.liste' in directory '/etc/apt/sources.list.d/'

Hello,

every time I start an update with openHAB-config I get the following message:
Ignoring file ‘openhab.liste’ in directory ‘/etc/apt/sources.list.d/’ as it has an invalid filename extension
Can someone help me with this.

Many thanks

Assuming you have a proper /etc/apt/sources.list.d/openhab.list file all you need to do is remove the one ending in .liste. If not, you need to look inside the .liste file and see if it’s correct. If so change the name of the file to end in .list.
