I'm having strange problem on 1 of my Mikrotik NASes.

Currently running 6.32.4 and I'm trying to upgrade to 6.34.3.

Going through System -> Packages > Download and Install - everything passes normally, I can see the .npk in "File" menu but after reboot it's still on the old (same) version.

For Some reason it's not getting upgraded.

Any ideas what could be the problem and what can be tested?

I found wireless-6.34.npk file in "Files" with size of 0.

Deleted it and after another attempt to upgrade - Voila! It works now.

I don't have any idea how this zero file has appeared at all.
