qt qt UPGRADE

Affected: >= 5.12.0 and < 5.15.17 · >= 6.0.0 and < 6.2.12 · >= 6.3.0 and < 6.5.5 · >= 6.6.0 and < 6.6.2

Fixed in: 5.15.17, 6.2.12, 6.5.5, 6.6.2

Safe to downgrade to: a release before 5.12.0

1. Check installed version

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

2. UPGRADE to 5.15.17 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade qt

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 5.12.0 (Debian / Ubuntu)

apt-cache madison qt sudo apt install qt=<VERSION_BEFORE_5.12.0> sudo apt-mark hold qt

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

dnf --showduplicates list qt sudo dnf downgrade qt-<VERSION_BEFORE_5.12.0> sudo dnf versionlock add qt

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.
