ASA 5510 cannot be upgraded

[kpoon]

Hello,

I have been trying to upgrade the ASA 5510 8.2.1 via ASDM upgrade wizard, or upload file manually via ASDM. I keep getting error

Erro occured in performing File Transfer

server returned HTTP response code: 500 for URL:

https://192.168.10.1/admin/disk0/asa822-k8.bin

I've tried asa824-k8.bin also with same result.

Only success I had was upgrading ASDM to 6.2(5)53

Anyone knows why?

Hi,

Please go through the document for ASDM image upgrade below, make sure all teh steps are correct andeven if it doesn't work out, try upgrading from the CLI as well:

Hope this helps.

Thanks,

Also, please check the falsh memeory available and if everything seems fine but still you face issues, reload the firewall, that should clear out any issues with firewall.

Thanks,

Varun

I solved this issue little differently after spending few hours debugging the issue.

Issue:  ASDM throwing "asdm file transfer 500 http response" while doing a file transfer(asa firmware only) or upgrading the image.

Summary:

I was on 9.0.4 and was trying to upgrade to 9.1.6. 

It had throwed the error multiple times despite of the system reboot and enough disk room.

Later while i was going through the release notes, i figured i can not upgrade straight from 9.0.4 to 9.1.6 and i have to follow the upgrade path.

Then i upgraded to 9.1.2 and then to 9.1.6. This has resolved the underlying "500" http response issue.

So the issue was with the upgrade path in my case and i would suggest it is worth checking(release notes) this as a first step...

Root Cause:

upgrade path was the the root cause.

Recommendation to Cisco:

Error handling by ASDM in this case was not quite relevant. It should have throw a proper text message  along with http response code.

I rebooted the ASA, then I can upgrade.

Thanks.
