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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade youtrack

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 2024.3.44799 (Debian / Ubuntu)

apt-cache madison youtrack sudo apt install youtrack=<VERSION_BEFORE_2024.3.44799> sudo apt-mark hold youtrack

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

dnf --showduplicates list youtrack sudo dnf downgrade youtrack-<VERSION_BEFORE_2024.3.44799> sudo dnf versionlock add youtrack

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.
