ibm aspera faspex UPGRADE
Affected: >= 5.0.0 and < 5.0.16
Fixed in: 5.0.16
Safe to downgrade to: a release before 5.0.0
1. Check installed version
apt-cache policy aspera-faspex || rpm -q aspera-faspex || aspera-faspex --version
2. UPGRADE to 5.0.16 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade aspera-faspex
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade aspera-faspex
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 5.0.0 (Debian / Ubuntu)
apt-cache madison aspera-faspex
sudo apt install aspera-faspex=<VERSION_BEFORE_5.0.0>
sudo apt-mark hold aspera-faspex
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list aspera-faspex
sudo dnf downgrade aspera-faspex-<VERSION_BEFORE_5.0.0>
sudo dnf versionlock add aspera-faspex
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.
