The file /usr/bin/qrcode is contained in the packages
* go-qrcode/0.0~git20200617.da1b656-4+b14 as present in forky|unstable
* go-qrcode/0.0~git20200617.da1b656-4+b17 as present in forky|unstable
* node-qrcode/1.5.4-1 as present in forky|unstable
Attempting to coinstall these packages results in an unpack error from dpkg.
I'm assigning the bug to node-qrcode for now as it was uploaded later.
Generally, I think the name /usr/bin/qrcode is too generic to be owned by a
singular tool and both packages should rename it.
Kind regards
