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

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

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

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.
