techsmith snagit UPGRADE

Affected: >= 11.2.1 and <= 20.0.3

Fixed in: newer than 20.0.3

Safe to downgrade to: a release before 11.2.1

1. Check installed version

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

2. UPGRADE to newer than 20.0.3 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade snagit

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 11.2.1 (Debian / Ubuntu)

apt-cache madison snagit sudo apt install snagit=<VERSION_BEFORE_11.2.1> sudo apt-mark hold snagit

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

dnf --showduplicates list snagit sudo dnf downgrade snagit-<VERSION_BEFORE_11.2.1> sudo dnf versionlock add snagit

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.
