Seen a behaviour with the occ command, when run on a 10.4 server, which I consider bad UX:
root@dmitry-oc-public:/tmp# occ market:install -l wopi-1.4.0.tar.gz
: App does not provide an info.xml file
The wopi-1.4.0.tar.gz contains an info.xml which requires a server min version of 10.5.
The error message is misleading.
Expected behaviour: It should say instead: "Error: requires min-version 10.5"
