webdav neon UPGRADE

Affected: >= 0.19.0 and < 0.24.5

Fixed in: 0.24.5

Safe to downgrade to: a release before 0.19.0

1. Check installed version

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

2. UPGRADE to 0.24.5 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade neon

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 0.19.0 (Debian / Ubuntu)

apt-cache madison neon sudo apt install neon=<VERSION_BEFORE_0.19.0> sudo apt-mark hold neon

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

dnf --showduplicates list neon sudo dnf downgrade neon-<VERSION_BEFORE_0.19.0> sudo dnf versionlock add neon

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.
