usememos memos DOWNGRADE

Affected: 0.22.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.22.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.22.0 (Debian / Ubuntu)

apt-cache madison memos sudo apt install memos=<VERSION_BEFORE_0.22.0> sudo apt-mark hold memos

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list memos sudo dnf downgrade memos-<VERSION_BEFORE_0.22.0> sudo dnf versionlock add memos

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.
