Multicast package not installing on HAP AC

Router FW: 6.46.1
No packages installed manually before, plenty of space.
Put multicast-6.46.1-mipsbe.npk over FTP and can see it in the file list. (HAP AC is mipsbe as far as I see on resources tab)

Rebooted the router, but nothing happens. The npk file is there and there is no message about it in the log.

Any clues? :frowning:

Is there anything in log about it? If there’s nothing, then npk file location is probably not right.

Nothing in logs.
When joining via FTP I see that root folder’s path is “/flash”. (with no way to get to the / folder)

Uploaded file via UI to the actual root folder, and it worked, thanks.
