not enough free disk space for update

guyc

When I start my orangepi PC2, I receive the message that there are update available for Ubuntu.
After accepting the installation of the updates, I receive the message
' Not enough free disk space . Update needs 48 M free space on disk /boot. Please fee at least an additional 9298 k ..........'

When I see in the properties, :
usage 9,6 of 15,2 GB free ( 36% used)

Strange, I have no idea why an update would need that much space in /boot.
Your /boot is only 50M so you can try to move (BUT KEEP!) your files from /boot and do the update.
From what I see you've installed Ubuntu on the internal memory, so if you decide to move everything out of /boot, be sure to have ready SD card in case anything go wrong. In this case - boot from and SD card and move back the files to /boot

Many thanks, but I don't understand. As far as I know, the orangepi boots from the SD card. With no SDcard, nothing happens. Even no green and red led.

this worked for one time

sudo apt-get purge $( dpkg --list | grep -P -o "linux-image-\d\S+" | grep -v $(uname -r | grep -P -o ".+\d") )

Afterward I received again the message that there was an update available of 227 kB, when I accepted the update, I receive the same message that the system needed 92 MB to do the update and stopped.
