llamaindex llamaindex UPGRADE

Affected: >= 0.12.19 and < 0.12.21

Fixed in: 0.12.21

Safe to downgrade to: a release before 0.12.19

1. Check installed version

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

2. UPGRADE to 0.12.21 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade llamaindex

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 0.12.19 (Debian / Ubuntu)

apt-cache madison llamaindex sudo apt install llamaindex=<VERSION_BEFORE_0.12.19> sudo apt-mark hold llamaindex

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

dnf --showduplicates list llamaindex sudo dnf downgrade llamaindex-<VERSION_BEFORE_0.12.19> sudo dnf versionlock add llamaindex

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.
