Issue: Unable to recover files from /var/lib/letsencrypt/temp_checkpoint
# certbot 1.7.0, CentOS 7 certbot --nginx -d site.domain.com # echo Saving debug log to /var/log/letsencrypt/letsencrypt.log Unable to recover files from /var/lib/letsencrypt/temp_checkpoint Incomplete or failed recovery for /var/lib/letsencrypt/temp_checkpoint Unable to revert temporary config
I did. Solved:
yum update mv /var/lib/letsencrypt /var/lib/letsencrypt.original
sed -i 's|^Exec=.*$|Exec=bash -c "QT_SCALE_FACTOR=1.3 /opt/viber/Viber" %u|g' /usr/share/applications/viber.desktop

Asterisk put logs to /var/log/syslog
Affected OS: Ubuntu, Debian 9
# Step1: create file for rsyslog
cat << EOF > /etc/rsyslog.d/10-asterisk.conf
if \$programname == "asterisk" then { stop }
EOF
# Step2:
systemctl restart rsyslog.service
Creation of file from pillar simple list with Jinja template will be create empty line, in top or bottom of file, dependence for template syntax.
You can not create file without empty lines.
#!/usr/bin/python
from jinja2 import Template
d = {'testlist':['item1','item2','item3']}
tmpl = '''{%- for item in testlist %}
{{ item }}
{%- endfor %}'''
t = Template(tmpl)
print( t.render( d ) )

WARNING: The vboxdrv kernel module is not loaded. Either there is no module

You will not be able to start VMs until this problem is fixed.
Description from vendor https://docs.saltstack.com/en/latest/topics/best_practices.html
My opinion: NEVER USE
It is not possible to see the values from this map on node or salt-master by any command, like:
pillar.get pillar.items
State will applied to the minion, even when node (or/and any parent class) has no any pillar data to this state.

xfce4-hardware-monitor-plugin has been removed from relevant packages.
It’s so bad.
This is the best plugin for hardware monitoring! Thank you, OmegaPhil!
Will install it manually.

* a02a81b 2012-06-19 | added option to set custom peer status using UserEvent [Diego Aguirre]
DONT WORK - Lost connection to server each 3-4 seconds.
* 777df26 2012-04-24 | changes [Diego Aguirre]
WORK
Selected version bbce290 2018-01-23
Commented lines in monast.py:
server.pushTask(server.ami.command, "database show") \
.addCallbacks(onCustomPeerStatus, self._onAmiCommandFailure, errbackArgs = (servername, "Error Requesting Custom Peer Status from ASTDB"))
Now connection to asterisk not lost.
Reason on issue: too much records in database, long time of executing request ‘database show’.
$ asterisk -rx 'database deltree q-answered' 156568 database entries removed.
