Server Version#:1.21.1.3830
Player Version#:

Here is the output of trying to install the 1.21.1.3830 update. It gives an error for not enough memory, but I have plenty of memory available. Any suggestions for fixing this?

‘free’ is for memory … not disk space.
Confirm you have enough disk space available.

‘df -a’

I’ve seen that before. I think it’s related to an IR driver.
That driver conflicts with Ubuntu.

Folks seemed to be in the clear once the driver was removed.

It’s strange it’s showing here as that should be showing for any packages being installed. I do nothing special during installation.

If this is related to HD space, I’d like to know why it’s not complaining about lack of disk space as it unpacks the file. (done before it prints "Now Installing … ")

There’s plenty of free space. It appears that the input21 refers to a nonexistent device, and I don’t see any driver. How do I remove the device, and why is Plex install trying to access it?

ChuckPa,
I found that thread, and removing lirc did the trick. Thanks for the direction.
