Safe to downgrade to: a release before 2.20.1-0ubuntu1

1. Check installed version

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

2. UPGRADE to 2.20.1-0ubuntu2.30 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade apport

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 2.20.1-0ubuntu1 (Debian / Ubuntu)

apt-cache madison apport sudo apt install apport=<VERSION_BEFORE_2.20.1-0ubuntu1> sudo apt-mark hold apport

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

dnf --showduplicates list apport sudo dnf downgrade apport-<VERSION_BEFORE_2.20.1-0ubuntu1> sudo dnf versionlock add apport

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.
