Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Tanya Tereshchenko 2021-05-07 20:51:34 UTC 
Description of problem:

pulp_rpm 3.10 always publishes metadata with sha256 checksum type(in repomd.xml).
pulp 2 decides based on metadata type, which checksum type to expect for content as well (in primary.xml).
If one syncs a repo with md5 checksumtype (for content) using on_emand policy, sha256 checksum won't be available, and this is where pulp2 on_demand sync fails.
Both content migration and sync into main Satellite are affected.

Steps to Reproduce:
- Sync using on_demand policy a non-sha256 repo into a main Satellite (Pulp 3).
- Trigger capsule (Pulp 2) sync, also on_demand(this is important) of a repo from step 1.

A workaround is to perform a capsule sync with on_demand policy.

A workaround is to perform a capsule sync with the *immediate* policy.

Comment 12 Tanya Tereshchenko 2021-06-14 10:35:31 UTC 
This issue is only partially fixed and can be fully fixed only in the later versions (the ones which use pulp_rpm 3.13+).

The majority of repositories use sha256 checksum type, so this issue affects the small amount of repositories.
There are 2 workarounds available:
 - use immediate policy with capsule sync
 - on the main Satellite explicitly specify a checksum type which needs to be used for a repo (if remote source uses md5, specify md5 to be used; sha1 -> sha1, etc)

Comment 17 Vladimír Sedmík 2021-07-15 19:10:09 UTC 
Verified with:
1) Satellite 6.10.0 snap 9 (upgraded from 6.9.4 snap 1), python3-pulpcore-3.14.0-1.el7pc.noarch
2) Capsule 6.9.4 snap 1, pulp-server-2.21.5.2-1.el7sat.noarch

Sync of an on-demand sha512 repo to the on-demand Capsule succeeded, no errors seen in the journal, repo created in capsule:/var/lib/pulp
