CUCM 8.5(1)SU2 (Restricted) Upgrade File Integrity on CCO

[alf]

Hello Team,

does anybody have installed this Upgrade File from CCO yet ?

I´ve got the message "error accessing the upgrade file" either mounting the ISO-File or transferring it with sftp.

(The transfer itself works fine). The File size of the downloaded file is that from CCO

(4.522.868.736 UCSInstall_UCOS_8.5.1.12900-7.sgn.iso), however if I look for the md5

checksum this is different as described on CCO (mine is 3232db479948c65312e278769490a41d

vs. CCO´s md5 is 26289d2f3074a2880aaf4102d8aeadc3)

I did the download twice with the same result, so I ask around, if anybody has been successful with this

File ?

Thx

Alfred

futher information:

the exact error message is:

Status                                                                    Error encountered: An unknown error occurred while accessing the upgrade file

but looking for previous discussion topics this might be misleading...

best regards,

Alfred

Hi Alfred,

I tested it from my side. I downloaded the copy from CCO and calculated the MD5 on it:

file: UCSInstall_UCOS_8.5.1.12900-7.sgn.iso

md5: 26289d2f3074a2880aaf4102d8aeadc3

I used this tool to calculate the MD5:

http://download.cnet.com/MD5-Checksum-Calculator/3000-2092_4-10964258.html

So I would suspect this is an issue with your connectivity(proxy server?) or client. Could you try from a different browser and/or different internet access?

Thx for your evaluation.

I doublechecked with the md5-Tool you mentioned, same result (my download file has a different checksum than

yours). But I wonder myself, why I am able to extract the ISO-File to a normal file-package. Shouldn´t there

also run of checksum-proof ?

I tried in my office as well as at home, but I will another try will IE instead of mozilla.

best regards

Alfred

Did some more attempts to download the code from my office, with and without Download-Manager,

always got the same but wrong md5 checksum mentioned above.

I will follow on this issue via TAC.

Hi Alfred,

TAC cannot help with this as such (except for republishing), you would need to contact cco support for this.

I manually published the UCSInstall_UCOS_8.5.1.12900-7.sgn.iso for you, maybe that works for you?

Thx,

Hi Bruno,

Many thanks for helping me.

Trying now to download via special file access. Keep you informed.

Thx again.

Hi Bruno,

can the MD5 Checksum be dependent on the client OS platform ?

I have Windows XP 2002 Professional SP3 (32 Bit) installed on my client

computer.

Hi Bruno,

the Special-File Access with your mentioned Checksum Verification

program works fine. So I will proceed with this file.

Many Thanks !

Mit freundlichen Grüßen / Kind regards

Same problem here, downloaded and checked MD5 hash:

3232db479948c65312e278769490a41d

I then ran a different MD5 Checker which gave the correct hash of

26289d2f3074a2880aaf4102d8aeadc3

Poped the file of our SFTP server and it fialed because the MD5 reported to be the wrong hash, I then burnt the ISO to a DVD placed it in the drivre of each of the nodes and all went well.
