I am using Artifactory Pro version 6.8.1.
I have created a conda virtual repository with conda remote setup.
Initially it was fine, but lately i have this error where i run
conda install -y <package_name>
it returns
MD5MismatchError: Conda detected a mismatch between the expected content and downloaded content

I try to run
conda clean --all
but it still shows the MD5mismatch error. Any suggestion to fix this MD5 exception for Artifactory ?
I managed to find a solution somehow, just to share to those who are having the same issue.
Artifactory generates its own checksum and compares it with the downloaded checksum.
For more details :
What i did was,
1) Go to Artifactory. Find the downloaded artifact with issues on checksum mismatch.
2) Click on the artifact, by right it will show
Checksums
SHA-256: XXX(Uploaded: Identical)
SHA-1: XYZ (Uploaded: None)
MD5: XYY(Uploaded: None)
Client did not publish a checksum value.
If you trust the uploaded artifact you can accept the actual checksum by clicking the
'Fix Checksum' button.
3) Check the downloaded MD5 in the remote repository, the one Artifactory is connecting and downloading the package from.
4) Verify it is same, and once verified, click the Fix the checksum button.
5) This should solve the MD5 error issue. Hopefully it helps.
