Error writing blog Digest did not match, expected sha256:5**, got sha256:0**

Troubleshooting


Problem

When we run the cpd-linux install or apply patch command,
./cpd-linux patch --repo ../repo.yaml --assembly wkc --version 3.2.72 --patch-name cpd-3.0.1-wkc-patch-8 --action download  --download-path ./wkcpatch8
we may get "Error writing blob" and "Error in handling image request".

​

Symptom

In air gap env, client needs to download Cloud Pak for Data from another machine that can connect to the internet. After the download complete, they need to copy these images to the server that can be connected from the cluster. While during the copy and paste operation,it might be image crush or mismatch happen. The following error can be one of the symptoms when we run the install command.

Cause

There might be some problems such as I/O or network problems during the image copy and paste operation that caused the images to crush.

Environment

Cloud Pak for Data v301

Resolving The Problem

Do double check the image md5sum result to see if it is the same as the original one. Such as use the following command:
md5sum is-db2xmeta-image-----b104-CP4D-3_0_1-b56.tar
it will return a string for this image, such as:

768a9bb95aba3e8acb965c775e15ab21  is-db2xmeta-image-----b104-CP4D-3_0_1-b56.tar
Make sure the two returns are the same when you run md5sum command on the airgap server and the download server.
If they are not the same,then need to copy this image again and check its md5sum result.
