snipeitapp snipe-it UPGRADE

Affected: >= 8.5.0 and < 8.7.0

Fixed in: 8.7.0

Safe to downgrade to: a release before 8.5.0

1. Check installed version

apt-cache policy snipe-it || rpm -q snipe-it || snipe-it --version

2. UPGRADE to 8.7.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade snipe-it

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade snipe-it

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 8.5.0 (Debian / Ubuntu)

apt-cache madison snipe-it sudo apt install snipe-it=<VERSION_BEFORE_8.5.0> sudo apt-mark hold snipe-it

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

dnf --showduplicates list snipe-it sudo dnf downgrade snipe-it-<VERSION_BEFORE_8.5.0> sudo dnf versionlock add snipe-it

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.
