http fetcher http fetcher library DOWNGRADE

Affected: 1.0.0 · 1.0.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.0.0

apt-cache policy http-fetcher-library || rpm -q http-fetcher-library || http-fetcher-library --version

2. No fixed release: DOWNGRADE to a release before 1.0.0 (Debian / Ubuntu)

apt-cache madison http-fetcher-library sudo apt install http-fetcher-library=<VERSION_BEFORE_1.0.0> sudo apt-mark hold http-fetcher-library

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.
