Image file size is smaller

[Fab_BN]

Hello,

I want to upgrade my access point AP2802 ME from 8.3.102 to 8.6.101. Cisco provided me the .ZIP but I have a problem when I make the upgrade I have the message "Error, image file size is smaller than image + key + signature 0x02dac0f9: 0xdcaf495e".
I tried to convert to CAPWAP before making the upgrade, tip that I read on the Internet, but I have the same concern.
Here is the command I entered "archive download-sw / reload tftp: //192.xx.xx.xx/ap1g4".

I recall it being a *.tar file.  Are you giving it the whole tar file?

[Fab_BN]

Thank you. I am far from an expert in Cisco. So I followed the tutorials on the Internet.
I received a ZIP file that I unzipped, in there are 9 files. I put all these files on my TFTP server and I download the ap1g4 file. It weighs 47 MB.

The "archive" command normally works with archives. Trying giving it the zip file instead.

I tried with the full ZIP and I converted to TAR too, but it's still the same. Here is the message:

It says you have ran out of space "No space left on device".

You need to clean up the flash file system.

[Fab_BN]

can you tell me the command please

[Philip D'Ath]

Well, this will show you what is in the flash:

dir flash:
If you identify some things you can remove then use the "delete" command to delete them.

Thank you,

Hello,

It's a bug:

https://supportforums.cisco.com/t5/security-and-network-management/cisco-ap-2800-e-unable-to-upgrade/td-p/3325529

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCuz81074/?referring_site=bugquickviewredir

Should the firmware be downgraded to 8.2 then upgraded to 8.6 ?

[J. H.]

How did you resolve this?

The only tip I read about is: "convert to non-ME barbados". But it doesn't say how to convert to non-ME. I got AP2802i's.
