I copied: enigma2-plugin-softcams-oscam_11.704-emu-r798_all.deb into the Dreambox One in tmp.
So I run DCC.
I entered the decoder with ip and pass
I click on Telnet
I write on the line: dpkg -i /tmp/*.deb
I hit enter
It seems to have installed, so I restart the decoder.
But I don't find anything new.
