DCO 8.3.2 Upgrade Problem - Checksum Error

I am trying to upgrade DCO to version 8.3.2 from 8.2.12 and getting hash error below:

Upgrade failed with: SHA256 '51412d4a3f62b97f26592fd8b1c182bd12b500fc655aec4ee473613712603943' of the uploaded file does not match the expected SHA256 '51412D4A3F62B97F26592FD8B1C182BD12B500FC655AEC4EE473613712603943'!

Correct me if I am wrong but it looks the same to me except for the CAPS.

Can you help?

Hello Jakub.

I confirmed the hash you pasted is the correct hash for the 8.3.2 iso.

Can you share a screenshot of the webmin screen from where the upgrade was initiated?

Also, did you copy the iso to the DCO server and use a local path to the iso or did you specify a remote location so webmin had to upload the iso to the DCO server first? If the latter, please re-try initiating the upgrade with the iso file pre-copied to the DCO server and then using that local file path to the 8.3.2 ISO file.

Regards

Hi Jakub,

It appears you have mis-typed the SHA256 checksum.

I can reproduce the same behavior if I intentionally use the incorrect checksum ('51412D4A3F62B97F26592FD8B1C182BD12B500FC655AEC4EE473613712603943')

then I get the expected upgrade failure notification:

This is the correct checksum (all with small letters):

Perhaps your "Caps Lock" (on your keyboard) have been enabled and therefore all your entries have been with capital letters.

By using the correct checksum I could/can upgrade to 8.3.2 without any problem.  

Kind regards

Thank you for the solution Jef.

I have generated the ISO file checksum using powershell and the output hash string was in CAPS.

The fact that webmin upgrade tells you the correct hash should be in CAPS is misleading.

That is the reason why I used caps when pasting the hash into DCO during the upgrade.

Best regards
