ibm db2 mirror for i UPGRADE

Affected: >= 7.4 and <= 7.6

Fixed in: newer than 7.6

Safe to downgrade to: a release before 7.4

1. Check installed version

apt-cache policy db2-mirror-for-i || rpm -q db2-mirror-for-i || db2-mirror-for-i --version

2. UPGRADE to newer than 7.6 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade db2-mirror-for-i

sudo dnf upgrade db2-mirror-for-i

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 7.4 (Debian / Ubuntu)

apt-cache madison db2-mirror-for-i sudo apt install db2-mirror-for-i=<VERSION_BEFORE_7.4> sudo apt-mark hold db2-mirror-for-i

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

dnf --showduplicates list db2-mirror-for-i sudo dnf downgrade db2-mirror-for-i-<VERSION_BEFORE_7.4> sudo dnf versionlock add db2-mirror-for-i

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.
