ibm aspera console UPGRADE

Affected: >= 3.4.0 and < 3.4.5

Fixed in: 3.4.5

Safe to downgrade to: a release before 3.4.0

1. Check installed version

apt-cache policy aspera-console || rpm -q aspera-console || aspera-console --version

2. UPGRADE to 3.4.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade aspera-console

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade aspera-console

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 3.4.0 (Debian / Ubuntu)

apt-cache madison aspera-console sudo apt install aspera-console=<VERSION_BEFORE_3.4.0> sudo apt-mark hold aspera-console

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

dnf --showduplicates list aspera-console sudo dnf downgrade aspera-console-<VERSION_BEFORE_3.4.0> sudo dnf versionlock add aspera-console

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.
