jazzband django debug toolbar UPGRADE

Affected: >= 0.10.0 and < 1.11.1 · >= 2.0.0 and < 2.2.1 · >= 3.0.0 and < 3.2.1

Fixed in: 1.11.1, 2.2.1, 3.2.1

Safe to downgrade to: a release before 0.10.0

1. Check installed version

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

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade django-debug-toolbar

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 0.10.0 (Debian / Ubuntu)

apt-cache madison django-debug-toolbar sudo apt install django-debug-toolbar=<VERSION_BEFORE_0.10.0> sudo apt-mark hold django-debug-toolbar

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

dnf --showduplicates list django-debug-toolbar sudo dnf downgrade django-debug-toolbar-<VERSION_BEFORE_0.10.0> sudo dnf versionlock add django-debug-toolbar

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.
