On a Debian Stretch system at work, certbot was working but automatic renewals were not. The system is behind a proxy server and the
https_proxy environment variable was not being set when certbot ran unattended.
I wasted several hours tinkering with
/etc/cron.d/certbot before I realized that
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(3600))' && certbot -q renew
was preventing certbot from running if systemd was running.
The SAR for Nexus 5X is very hard to find on the web.
Go to http://www.lg.com/global/support/sar/sar. In the boxes at the bottom of the page, — Select Category — Mobile Phone, then search on LG-H790.
Results I get are:
-Europe & Middle East & Africa & Asia & Oceania
The highest SAR value for use at the ear is 0.607 W/kg (10 g) and when worn on the body is 0.397 W/kg (10 g) at 15mm
-USA & Canada
The highest SAR value for use at the ear is 1.25 W/kg (1 g) and when worn on the body is 1.28 W/kg (1 g) at 10mm

(Tax time issue.) I burned a data CD on Debian 7 using Brasero. When I attempted to mount the data CD to verify that it was readable, I got an error:
unknown filesystem type 'iso9660'. This was because iso9660 support was missing from my install. To solve this,
apt-get install fuseiso9660
