要約
Git operations, such as clones, fetches and pushes fail.
The Git client receives a 500 error, similar to the following while performing a Git operation:
error: RPC failed; HTTP 500 curl 22 The requested URL returned error: 500 fatal: expected flush after ref listingOn the server side, one or more Bitbucket nodes have the following error in the atlassian-bitbucket.log file:
The following was written to stderr:
fatal: unknown capability 'object-format=sha1'This error indicates that the Git version installed on that particular node does not recognize the object-format capability used in a repository.
The object-format capability, which was introduced in Git 2.28.0, specifies the supported hash algorithm for naming content in Git repositories. (Reference: Git 2.28.0 Protocol Capabilities)
This error suggests that there's a mismatch in the Git versions installed on the Bitbucket Data Center cluster nodes.
Some nodes have Git versions >= 2.28.0 installed that support the object-format capability while others have Git versions < 2.28.0, which do not support it.
環境
- Bitbucket Data Center instances with more than one node
- Nodes do not have the same Git versions installed
診断
One or more Bitbucket Data Center nodes report fatal: unknown capability 'object-format=sha1' errors in the atlassian-bitbucket.log file.

ソリューション
Check the Git versions installed on the cluster nodes and ensure that they all use the same version.
Upgrade Git on the nodes that still have version < 2.28.0 to match the Git version on other nodes.
Check the Bitbucket Supported Platforms page for the Git versions that are supported for your Bitbucket version:
- Bitbucket Data Center Supported Platforms (be sure to select the relevant Bitbucket version from the dropdown in the top right hand corner of the page)
