gitblit gitblit DOWNGRADE

Affected: 1.7.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.7.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.7.1 (Debian / Ubuntu)

apt-cache madison gitblit sudo apt install gitblit=<VERSION_BEFORE_1.7.1> sudo apt-mark hold gitblit

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

dnf --showduplicates list gitblit sudo dnf downgrade gitblit-<VERSION_BEFORE_1.7.1> sudo dnf versionlock add gitblit

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.
