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 6.4.0 (Debian / Ubuntu)

apt-cache madison qt-framework sudo apt install qt-framework=<VERSION_BEFORE_6.4.0> sudo apt-mark hold qt-framework

dnf --showduplicates list qt-framework sudo dnf downgrade qt-framework-<VERSION_BEFORE_6.4.0> sudo dnf versionlock add qt-framework

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
