obsidian obsidian UPGRADE

Affected: >= 0.14.0 and < 0.15.5

Fixed in: 0.15.5

Safe to downgrade to: a release before 0.14.0

1. Check installed version

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

2. UPGRADE to 0.15.5 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade obsidian

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 0.14.0 (Debian / Ubuntu)

apt-cache madison obsidian sudo apt install obsidian=<VERSION_BEFORE_0.14.0> sudo apt-mark hold obsidian

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

dnf --showduplicates list obsidian sudo dnf downgrade obsidian-<VERSION_BEFORE_0.14.0> sudo dnf versionlock add obsidian

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.
