apache roller UPGRADE

Affected: >= 1.0 and < 6.1.5

Fixed in: 6.1.5

Safe to downgrade to: a release before 1.0

1. Check installed version

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

2. UPGRADE to 6.1.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade roller

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade roller

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.0 (Debian / Ubuntu)

apt-cache madison roller sudo apt install roller=<VERSION_BEFORE_1.0> sudo apt-mark hold roller

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list roller sudo dnf downgrade roller-<VERSION_BEFORE_1.0> sudo dnf versionlock add roller

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.
