Safe to downgrade to: a release before 2026.1.0

1. Check installed version

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

2. UPGRADE to 2026.1.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade discourse

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 2026.1.0 (Debian / Ubuntu)

apt-cache madison discourse sudo apt install discourse=<VERSION_BEFORE_2026.1.0> sudo apt-mark hold discourse

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

dnf --showduplicates list discourse sudo dnf downgrade discourse-<VERSION_BEFORE_2026.1.0> sudo dnf versionlock add discourse

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.
