Update current installation first and reboot if pending.
- Add new repo for 1.34:
add-apt-repository ppa:iconnor/zoneminder-1.34
- Update using new repo:
apt-get update
- Perform upgrade:
apt-get full-upgrade
I kept the existing version of system-paths file rather than overwriting with new version.
- Remove repo for 1.32:
add-apt-repository --remove ppa:iconnor/zoneminder-1.32
