apache couchdb UPGRADE

Affected: < 3.2.3 · >= 3.3.0 and < 3.3.2

Fixed in: 3.2.3, 3.3.2

Safe to downgrade to: a release before 3.3.0

2. UPGRADE to 3.2.3 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

apt-cache madison couchdb sudo apt install couchdb=<VERSION_BEFORE_3.3.0> sudo apt-mark hold couchdb
