CCR1009 v7.16

We have trobule upgrading CCR1009 from 7.15.3 to 7.16
One CCR1009 running routeros and wireless package upgraded perfectlly.
Other running routeros, wireless and dude didnt.

Also, I have tried to upgrade to testing v7.16 rc5 and same thing happend.
check for upgrades —>> Download and install and after reboot same 7.15.3 version is there.

Something is probablly wrong with dude package.

Anything in the log that might be of help? I.e. enough free disk space?

After 1000 times of upgrades i forgot to chech the free space.
That was it.
Thank you for the hint.
