gitnoteapp gitnote DOWNGRADE

Affected: 3.1.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.1.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.1.0 (Debian / Ubuntu)

apt-cache madison gitnote sudo apt install gitnote=<VERSION_BEFORE_3.1.0> sudo apt-mark hold gitnote

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

dnf --showduplicates list gitnote sudo dnf downgrade gitnote-<VERSION_BEFORE_3.1.0> sudo dnf versionlock add gitnote

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.
