Flash-kernel fails while doing apt upgrade

[snehitha]

Impact :
while doing sudo apt upgrade for the first time , it exits at flash-kernel stage with below errors :

flash-kernel: deferring update (trigger activated)
/etc/kernel/postinst.d/zz-flash-kernel:
flash-kernel: deferring update (trigger activated)
Errors were encountered while processing:
 flash-kernel
needrestart is being skipped since dpkg has failed
E: Sub-process /usr/bin/dpkg returned an error code (1)

If we upgrade again , then upgrade is successful .
Attaching the log.

Thank you for reporting the issue with upgrading.

According to the log the problem was that a post installation trigger for flash-kernel was processed before processing the linux-image trigger.
