ibm i access client solutions UPGRADE
Affected: >= 1.1.2 and < 1.1.9.14
Fixed in: 1.1.9.14
Safe to downgrade to: a release before 1.1.2
1. Check installed version
apt-cache policy i-access-client-solutions || rpm -q i-access-client-solutions || i-access-client-solutions --version
2. UPGRADE to 1.1.9.14 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade i-access-client-solutions
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade i-access-client-solutions
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 1.1.2 (Debian / Ubuntu)
apt-cache madison i-access-client-solutions
sudo apt install i-access-client-solutions=<VERSION_BEFORE_1.1.2>
sudo apt-mark hold i-access-client-solutions
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list i-access-client-solutions
sudo dnf downgrade i-access-client-solutions-<VERSION_BEFORE_1.1.2>
sudo dnf versionlock add i-access-client-solutions
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.
