djangoproject django UPGRADE

Affected: < 5.2.17 · >= 6.0 and < 6.0.8

Fixed in: 5.2.17, 6.0.8

Safe to downgrade to: a release before 6.0

1. Check installed version

apt-cache policy django || rpm -q django || django --version

2. UPGRADE to 5.2.17 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade django

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade django

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 6.0 (Debian / Ubuntu)

apt-cache madison django sudo apt install django=<VERSION_BEFORE_6.0> sudo apt-mark hold django

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list django sudo dnf downgrade django-<VERSION_BEFORE_6.0> sudo dnf versionlock add django

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.
