Sysupgrade error messages

Sun May 25 13:30:14 PDT 2025

I’m seeing:

Command failed: Command failed

when I run sysupgrade.  This appears immediately after the list of files backed up:

No one wants to see their upgrade failing.

Should I be worried?  The message is a little vague.

Throwing a -x into the end:

so it’s the final command:

ubus call system sysupgrade "$(json_dump)”

that’s failing.
