hi, I came across this post while searching for origin/solution for a FATAL message around LZ4 during deb package update via xbian-config. The process ends with a message complaining LZ4 compression is active while kernel 4.19.75+ doesn't support it.
I am currently on a 4.9.x kernel, is the correct solution to hold the linux-image-bcm2836 package for now? if not, how can I upgrade the kernel via xbian-config without putting the system at risk? for instance it seems `xbian-compress` is not always a good idea, so what would I need to check before I run such commands?
thanks in advance, and sorry for hijacking this post

You don't have to check anything before. All necessary checks are done by xbian-compress automatically
You generally have 2 opportunities:
1) run xbian-compress
2) make complete image backup (after disabling compression in /boot/cmdline,txt) and flash this image on (new) sd-card

thanks for the confirmation. I was confused by your earlier comment that it would need ample free disk space to correctly run. I ran the command
Code:
xbian-compress compress --compress=lzo
