AttributeError: '_pygit2.Blob' object has no attribute 'hex'

 

As seen in the last line of the traceback message, the pygit2 library is unable to access an object attribute called "Blob". The exact cause of this issue is unknown, but more reading can be done at the following link in the community forums. https://github.com/saltstack/salt/issues/67017

 

 

Environment

Aria Config - all versions

SaltProject - 3006.9+

Resolution

Downgrade the pygit2 library from the latest installed version to an older version. Run the following steps on your Salt master(s). 

  1. Create a snapshot of your Salt master VM just in case
  2. Stop the Salt master daemon
    1. systemctl stop salt-master
  3. Run "salt-pip uninstall pygit2" to remove the current version of the library
  4. Confirm that the "patchelf" package is installed on your Salt master
    1. For RHEL based Salt masters, run "dnf install patchelf" 
    2. For Debian based Salt masters, run "apt install patchelf"
  5. Install version 1.14.1 of the pygit2 library with "salt-pip install pygit2==1.14.1" 
    1. This requires access to the Internet for direct installation. 
    2. This package can also be downoaded directly from PyPI here, https://pypi.org/project/pygit2/1.14.1/
      1. Once uploaded to the Salt master, install with salt-pip install /absolute/path/to/file
  6. Review the output carefully to ensure the module was installed successfully and that there were no errors during the installation
    1. If there are errors, then please check the error for any possible missing packages.
    2. If you see a message about being able to upgrad PIP itself, this is not necessary
  7. Clear the cache on the Salt master with "rm -fRv /var/cache/salt/master/gitfs"
  8. Start the Salt master daemon with "systemctl start salt-master"
