Description Hao Chang Yu 2018-06-06 02:28:55 UTC 
When the checksum type of the upstream repository changed, syncing a "on_demand" repository will fail with the following error:
------------
Checksum type "sha1" is not available for all units in the repository. Make sure those units have been downloaded
------------

When syncing a repository, Pulp will update the checksum type in the repo scratchpad to match the checksum type of the upstream repository, but the checksum_type configuration in the distributor will remain no change. This will cause the above error due to data/configuration inconsistency.

The "get_repo_checksum_type" function in [1] will attempt to save the checksum type to the distributor configuration if it is not already set. In my opinion, It should not save the checksum type after falling back to the scratchpad. If the checksum type for the distributor is not explicitly set, it should always fallback to the scratchpad.

In other word, the distributor should follow the checksum type of the metadata when it is not explicitly set to use other checksum type by the user.

Comment 19 David Davis 2018-11-06 12:51:59 UTC 
Anand,

As the customer experienced this problem without having changed the checksum_type, then this is the same bug.
Comment 27 David Davis 2018-11-29 17:36:32 UTC 
I just went through this so here are the steps to reproduce.

On your Satellite box:

$ mkdir /myrepo
$ chmod -R 777 /myrepo
$ cd /myrepo
# wget some packages
$ createrepo -s sha1 /myrepo

Now create a repo and set the feed url to "file:///myrepo/" and the download policy to "On Demand" and sync it.

Now back on your Satellite box:

$ cd /myrepo
$ createrepo -s sha256 /myrepo

And now sync again. If it doesn't error, you are good. Also, confirm the # of packages.
Comment 29 jcallaha 2019-01-17 21:50:51 UTC 

I followed the steps outlined in #27.
