Post Upgrade:
|
||||||
|
|
||||||
|
Install systemd service files and remove upstart scripts:

||||||
|
|
||||||
|
|
||||||
|
rm /etc/init/pandora*
|
||||||
|
/srv/pandora/ctl install
|
||||||
|
|
||||||
|
possibly adjust settings in /srv/pandora/pandora/gunicorn_config.py
|
||||||
|
|
||||||
|
Stop all pan.do/ra processes (run as root):
|
||||||
|
|
||||||
|
/srv/pandora/ctl stop
|
||||||
|
|
||||||
|
Enable pan.do/ra PPA again (run as root):
|
||||||
|
|
||||||
|
sed -i "s/^# deb/deb/g" /etc/apt/sources.list.d/j*.list
|
||||||
|
apt update; apt upgrade; apt autoremove; apt clean
|
||||||
|
|
||||||

New version of Postgres requires database migration (run as root):

|
|
||||||
|
apt remove postgresql-9.3 postgresql-contrib-9.3 postgresql-client-9.3
|
||||||
|
systemctl restart postgresql
|
||||||

cd /srv/pandora
|
||||||
|
rm -r lib/python2.7/site-packages/pip-* bin/pip* bin/python*
