astropy astropy DOWNGRADE

Affected: 5.3.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 5.3.2

1. Check installed version

pip show astropy

2. No fixed release: DOWNGRADE to a release before 5.3.2

pip index versions astropy pip install "astropy<5.3.2"

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
