Issue: Unable to recover files from /var/lib/letsencrypt/temp_checkpoint

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

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.

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.

It’s so bad.
Will install it manually.
