Error while running update now

Issue :

Are you getting this error ??

root@server1 [/tmp]# /scripts/updatenow
Updating /scripts…rename .sysup.kcMbDT -> sysup : Operation not permitted
rsync error: some files could not be transferred (code 23) at main.c(1045)
Done

Fix:

Very simple, check the attributes of the file listed in error.
In this case, sysup had immutable attributes.
