As an Admin I downloaded the qpkg file Entware_1.00std.qpkg to my laptop and opened “install manually” in AppCenter. Klick “Browse” and selected the file.
After some wait I got an icon in the AppCenter, but not on desctop.
Left klick-klick the icon opened a window with a hammer and link “Open”, which did nothing.
Log out and log in as basic user. THe icon is there, but does not more than before.
It’s a command-line utility for installing other command-line utilities. You access it remotely from your client device via SSH or Telnet (depending on your preference), or via the console by direct connection to your NAS with a monitor and keyboard (if supported).
I suggested it as your OP mention the vi editor, so I assumed you knew how to navigate via the command-line.
All QPKGs get an icon in the App Center so you can see what’s installed, and perform basic tasks on each QPKG. It doesn’t mean there’s a web UI to go along with the application inside the QPKG though.
After installing Entware and those other programs (Nano, Micro, TextEditor) I tried to find them and run them in CLI but with no success. There is no man pages nor I have found any other documentation.
I have used Linux for about 35y now, written a lot of programs and been working in a university helpdesk.
Just now my NAS is tied copying some 350GB of data from my home server
