7.2 Download CRIMA1161E ERROR: Failed to find required installation files

Verifying IBM ELM 7.2 Download Checksum

IBM Engineering Lifecycle Management (ELM) 7.2 download packages include a SHA256 checksum file. This checksum is used to verify that the downloaded ZIP file is complete, has not been corrupted during download, and matches the file published by IBM.

Example package:

JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip
JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256

What checksum verification does:

Checksum verification confirms that the downloaded file is complete. It also detects corruption caused by interrupted or failed downloads, confirms that the file matches IBM's published SHA256 value, and helps prevent installation issues caused by damaged repository ZIP files.

Checksum verification does not install or modify the ELM package. It only validates the downloaded file before you use it with IBM Installation Manager.

Windows verification steps

Step 1: Download both files

Download the ELM 7.2 repository ZIP and the matching checksum file into the same folder.

C:\Downloads\JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip
C:\Downloads\JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256

Step 2: Open Command Prompt or PowerShell

Open Command Prompt or PowerShell and change to the download folder.

cd C:\Downloads

Step 3: View the IBM-provided checksum

Run the following command:

type JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256

Example output:

e500c2ecfc05f69d09bedc307279b17b70310ab523a35e16a3aeb6b773ab0d6c *JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip

Step 4: Calculate the SHA256 checksum of the downloaded ZIP

Run the following command:

certutil -hashfile JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip SHA256

Example output:

SHA256 hash of JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip:
e500c2ecfc05f69d09bedc307279b17b70310ab523a35e16a3aeb6b773ab0d6c
CertUtil: -hashfile command completed successfully.

Step 5: Compare the values

Compare the SHA256 value shown by certutil with the value in the .sha256 file. If both values are identical, the verification has passed.

Successful Windows result:

The calculated SHA256 value matches the value in the IBM checksum file. The downloaded ELM 7.2 repository ZIP is intact and can be used.

Failed Windows result:

If the values do not match, do not install from this ZIP. Delete the file, download it again, and repeat the checksum verification.

Linux verification steps

Step 1: Download both files

Download the ELM 7.2 repository ZIP and the matching checksum file into the same directory.

/home/elm/downloads/JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip
/home/elm/downloads/JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256

Step 2: Go to the download directory

cd /home/elm/downloads

Or, if the files are in the user's Downloads directory:

cd ~/Downloads

Step 3: Confirm both files exist

ls -lh JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip*

Step 4: View the IBM-provided checksum

cat JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256

Example output:

e500c2ecfc05f69d09bedc307279b17b70310ab523a35e16a3aeb6b773ab0d6c *JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip

Step 5: Automatically verify the ZIP using the checksum file

sha256sum -c JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256

Expected successful output:

JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip: OK

Successful Linux result:

If the command returns OK, the downloaded IBM ELM 7.2 repository ZIP matches the IBM-published SHA256 checksum and can be used.

Failed Linux result:

If the command returns FAILED, the ZIP file may be corrupted, incomplete, or modified. Do not install from it. Delete it, download it again, and repeat the verification.

Linux manual verification alternative

You can also calculate the checksum manually:

sha256sum JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip

Then compare the output manually with:

cat JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256

Common mistake to avoid

Do not run the checksum check against the ZIP file itself:

sha256sum -c JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip

This is incorrect because the -c option expects a checksum file, not the ZIP file. Running this command against the ZIP may produce an error such as:

sha256sum: WARNING: lines are improperly formatted

The correct command is:

sha256sum -c JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256

Summary

Windows:

cd C:\Downloads
type JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256
certutil -hashfile JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip SHA256

Manually compare the SHA256 values.

Linux:

cd ~/Downloads
cat JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256
sha256sum -c JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip.sha256

Expected result:

JTS-DCM-CCM-QM-RM-JRS-ENI-repo-7.2.0.zip: OK

Once checksum verification returns OK, the IBM ELM 7.2 repository package is intact and can be extracted or used with IBM Installation Manager.
