typora typora UPGRADE

Affected: >= 1.0.0 and <= 1.7.0

Fixed in: newer than 1.7.0

Safe to downgrade to: a release before 1.0.0

1. Check installed version

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

2. UPGRADE to newer than 1.7.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade typora

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 1.0.0 (Debian / Ubuntu)

apt-cache madison typora sudo apt install typora=<VERSION_BEFORE_1.0.0> sudo apt-mark hold typora

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

dnf --showduplicates list typora sudo dnf downgrade typora-<VERSION_BEFORE_1.0.0> sudo dnf versionlock add typora

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.
