jpeg-compressor project jpeg compressor DOWNGRADE

Affected: 0.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.1

1. Check installed version

apt-cache policy jpeg-compressor || rpm -q jpeg-compressor || jpeg-compressor --version

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

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

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

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

Downgrade risk
