My current Raspi has MC 27 working perfectly. I use the VNC viewer that comes with the Raspi and it also works perfectly.
When I tried to update my SD card, after I copied it and booted with the card removed, I got an error that the USB boot device software needed an update and it gave me the link for the raspberry pi downloads. One of the help sites at raspberry cautioned about no warnings if the memory is insufficient ( https://www.raspberrypi.org/documentation/raspbian/updating.md ) and I thought I may not have enough room - especially with Wolfram Mathematica.
However, if I take the SSD and use Rasperries Mac software to load it with the latest operating system and I reboot....the SSD boots without a hitch.
Since the only thing I use the Raspi for is JRiver, I decided it might be less hassle to just load MC 27 again onto this fresh OS.
I installed VNC again and worked through the above steps - skipping over the X11 VNC --- but I had a typo on the public key and now I get an error as follows

I am thinking of wiping it and starting over again......unless you can see an easy fix
Wheaten:
Easy fix. There was a typo in the instruction. A "-" was added behind the "add". Code below is the correct one,
--- Code: ---wget -q "http://dist.jriver.com/mediacenter@jriver.com.gpg.key" -O- | sudo apt-key add
--- End code ---

That did it...thanks (I kept staring at that line)
Update: - I also increased the swap to 1024.....there's still a little lag.....I need to boot with the SD card to compare....I forget what it was like

Hello. I'm still having some troubles. Currently running MC 26 on Raspberry Pi 4 (one generation behind on everything, I guess). Anyway, I followed the instructions above on a new install, except that I just use RealVNC's vnc connect from a Windows 7 desktop, since that is what is packaged with Raspberry Pi OS. Everything runs OK if I have a hardware monitor, mouse and keyboard physically attached to the pi. But when I try to run headless, JRiver MC doesn't launch. So that's detach all hardware, wlan connect to local network, reboot, PuTTY connect to Pi via SSH from Win 7 remote desktop, run vncserver, then connect to Pi through vnc connect. I can see the desktop and run the native apps, but MC doesn't launch. Any suggestions?
Thanks!
Dennis in FL:
Hmmm...I also use the VNC....but with a Mac. I have my keyboard and mouse unplugged and it boots OK.
I can't remember doing anything in setup for that. I'm also booting from a USB drive.
Do you have the latest Raspi OS?
