dell appsync UPGRADE

Affected: >= 4.6.0.0 and < 4.6.1.0

Fixed in: 4.6.1.0

Safe to downgrade to: a release before 4.6.0.0

1. Check installed version

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

2. UPGRADE to 4.6.1.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade appsync

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 4.6.0.0 (Debian / Ubuntu)

apt-cache madison appsync sudo apt install appsync=<VERSION_BEFORE_4.6.0.0> sudo apt-mark hold appsync

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

dnf --showduplicates list appsync sudo dnf downgrade appsync-<VERSION_BEFORE_4.6.0.0> sudo dnf versionlock add appsync

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.
