I’m trying to upgrade the kernel snap on a UC 18 image running on an RPI4, but it’s failing due to lack of disk space in the
$ sudo snap list | grep pi-kernel pi-kernel 5.3.0-1021.23~18.04.1 117 18-pi/stable canonical* kernel $ sudo snap refresh pi-kernel error: cannot perform the following tasks: - Mount snap "pi-kernel" (119) (cannot install kernel: cannot extract "kernel.img" to "/boot/uboot/pi-kernel_119.snap": failed: "Write on output file failed because No space left on device", "writer: failed to write data block 166", and "Failed to write /boot/uboot/pi-kernel_119.snap/kernel.img, skipping")
Disk usage is as follows:
$ sudo df -h | grep -E "/boot|/writable" /dev/mmcblk0p2 30G 1.2G 27G 5% /writable /dev/mmcblk0p1 127M 106M 21M 84% /boot/uboot
The image was built with:
ubuntu-image snap --image-size 1536M ...
My questions are:
- Is there any way to recover from this?
- Should I consider increasing the size of the
/bootpartition as part of the image, and if so, how?
