Hello, all I am new to both Linux and Koha. I readily admit so. After several failed attempts to install Debian Linux on VirtualBox for Mac, I finally succeeded. Now I have trouble in installing Koha on the Debian VirtualBox. It fails at the first instruction in the Koha-Community instructions. When I open terminal and type this instruction $ wget -q -O- https://debian.koha-community.org/koha/gpg.asc | sudo apt-key add - terminal reports bash: sudo: command not found When I type this instruction $ wget -q -O- http://debian.koha-community.org/koha/gpg.asc | sudo apt-key add - terminal reports base: sudo: command not found I have even tried a variant from Joel Hertel's installation guide from a few years ago, to wit: $ su $ wget -q -O- http://debian.koha-community.org/koha/gpg.asc | apt-key add - What am I doing wrong? -- -- Charles.
