pi-hole pi-hole UPGRADE

Affected: >= 6.0 and < 6.4.3

Fixed in: 6.4.3

Safe to downgrade to: a release before 6.0

apt-cache policy pi-hole || rpm -q pi-hole || pi-hole --version

2. UPGRADE to 6.4.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade pi-hole

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade pi-hole

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 pi-hole sudo apt install pi-hole=<VERSION_BEFORE_6.0> sudo apt-mark hold pi-hole

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

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

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.
