Hi all,

I've installed the file from my local computer, but the error is the same as my first attach.

Is there some security configuration that i can change in my browser to prevent this error ?

It's a security problem of the browser, with "EDGE", Internet Explorer 11, and the last firefox the component won't install.

I use an old IE 10 and complete the installation.

Thanks a lot to all for the answers.

I'm having the same issue and

The "unsigned" error is a PI

The "unsigned" error is a PI cosmetic bug and should not affect your ability to install the update. 


Thanks Marvin - was slightly

Thanks Marvin - was slightly nervous about hitting the 'install' button until I found this post!


I recently had this unsigned

I recently had this unsigned error problem with both a Maintenance Release Patch in Prime, and the Device Pack update.

Apparently its an issue with how the browser downloads the file - the browser changes the extension to .zip. What makes it worse is that within the zip is actually a .ubf file and a .sig file?

To resolve, simply change the extension on the downloaded file from .zip to .ubf.

I hope this solves the problem for anyone looking at this (admittedly old) thread - this problem drove me up the wall!


Re: I recently had this unsigned

i was wondering why cisco would give out unsigned packages... this clarify's it all!
as usual I went unzipping and loaded the .ubf file without the .sig
ofc the .sig file is the certificate that the PI wants to ensure its from Cisco.
renaming the to filename.ubf did the trick like Cameronreeves said! thanks a lot for that imput.

Re: I recently had this unsigned

Thanks for this! I'm trying to write a MOP for customer on installing the DP and couldn't get it to work myself ... lol

Re: Cisco Prime 3.0 can't update device pack 3

I had this issue tonight.  Make sure to check the MD5 HASH with what is on Cisco's software page and that they match.   There are free MD5 Checks online.   That was my issue!
