dproxy dproxy DOWNGRADE

Affected: 0.1 · 0.2 · 0.3 · 0.4 · 0.5

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.1 (Debian / Ubuntu)

apt-cache madison dproxy sudo apt install dproxy=<VERSION_BEFORE_0.1> sudo apt-mark hold dproxy

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

dnf --showduplicates list dproxy sudo dnf downgrade dproxy-<VERSION_BEFORE_0.1> sudo dnf versionlock add dproxy

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.
