simogeo filemanager UPGRADE

Affected: >= 0.8 and <= 1.1 · >= 1.5.0 and <= 2.0.0

Fixed in: newer than 2.0.0

Safe to downgrade to: a release before 0.8

1. Check installed version

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

2. UPGRADE to newer than 2.0.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade filemanager

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 0.8 (Debian / Ubuntu)

apt-cache madison filemanager sudo apt install filemanager=<VERSION_BEFORE_0.8> sudo apt-mark hold filemanager

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

dnf --showduplicates list filemanager sudo dnf downgrade filemanager-<VERSION_BEFORE_0.8> sudo dnf versionlock add filemanager

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.
