easyphp webserver DOWNGRADE

Affected: 14.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 14.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 14.1 (Debian / Ubuntu)

apt-cache madison webserver sudo apt install webserver=<VERSION_BEFORE_14.1> sudo apt-mark hold webserver

dnf --showduplicates list webserver sudo dnf downgrade webserver-<VERSION_BEFORE_14.1> sudo dnf versionlock add webserver

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.
