Timeline

sqlite sqlite UPGRADE
Affected: >= 3.6.0 and <= 3.27.2
Fixed in: newer than 3.27.2
Safe to downgrade to: a release before 3.6.0
1. Check installed version
apt-cache policy sqlite || rpm -q sqlite || sqlite --version
2. UPGRADE to newer than 3.27.2 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade sqlite
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade sqlite
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 3.6.0 (Debian / Ubuntu)
apt-cache madison sqlite sudo apt install sqlite=<VERSION_BEFORE_3.6.0> sudo apt-mark hold sqlite
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list sqlite sudo dnf downgrade sqlite-<VERSION_BEFORE_3.6.0> sudo dnf versionlock add sqlite
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.
