No space left on device

I have purchased a Rock pi 4b and a samsung evo 64GB sd card. After booting ubuntu from image , I started installing lxde desktop. But i am getting error .

W: Some index files failed to download. They have been ignored , or old ones used instead
E: IO Error saving source cache
E: The package lists or status file could not be parsed or opened.

I have done df -h it shows

Try Armbian: https://www.armbian.com/rock-pi-4/

https://docs.armbian.com/#what-is-armbian

Try
sudo systemctl enable resize-helper.service

And then reboot.

Is desktop directly installed using armbian or we have to separately install it??

One more question. Please see the image attached. I am using 64 GB sd card and putted ubuntu server os image. but how come it is not showing this image. I am confused??

I don’t exactly understand your question … but there is no official Ubuntu support.

If you choose desktop image, yes, otherwise: armbian-config -> system -> enable desktop

Make sure to read a few things and especially 1st boot process. If you don’t create a normal user, there will be no desktop …

parted /dev/mmcblk0 5 64G
resize2fs /dev/mmcblk0p5
