Yeah, people like me often use one password on different machines, just because it's easier to remember. If this is blacklisted by being "weak", then it's a frustrating UX. Users don't like censorship, no matter what they do (and how dumb it is 
).
Maybe the best compromise is just to show a warning, and allowing the weak password afterwards.
I tried looking for a DRM Prime setting, but I could not find it. What is the menu path to that setting?
Settings -> Player -> Videos
The GUI has to be on "Advanced" or "Expert" mode (bottom left).
Is "the relevant nightly file" simply the latest img.gz from here?
Yes, take the one with the latest date.
Also do I need to decompress it first?
No. From SSH you can download and install (by reboot) without decompression:
cd /storage/.update
wget https://test.libreelec.tv/13.0/RPi/RPi2/<COMPRESSED_IMAGE_NAME>
rebootWhy the mac mini m4? Will it run LibreELEC?
Because it's a powerful mini PC with HDR. I don't see Kodi in the M4 app store, and we don't support it. However, it can run Linux, so you can autostart Kodi on it. Do some research, it's not our turf.
It's a bummer but it sounds kinda hard to get a powerful mini PC with correct HDR.
Get a Mac mini M4 or an Nvidia Shield.
That's why I thought the artist was on d_r_u_g_s. 
Do you get the same error without DRM Prime? You can disable DRM Prime in player settings.
What is "Mesa" ?
Home — The Mesa 3D Graphics Library
Are you saying if I got an Intel Beelink mini PC all would be ok?
Ask the Mesa guys.
Replace MyDrive by the drive name you'll find at /var/media.
So re-purposing some unused button on my LG Magic Remote still must be performed by the Black Art of that keymap XML.
It's not that bad.
Da Flex No, I prepare sd card using libreelec software, put sd card do rpi which was connected to PANASONIC (not samsung) TV.
Then I don't understand where the "SyncMaster" entry is coming from. Maybe your Panasonic TV is fake (Polish street market 
).
Hi, please change my username to KTI.
Done.
Activate log level 1 at advancedsettings.xml, and reboot. Then logging runs in background.
My theory is that he did the LE setup on a PC monitor. Then he went to the Panasonic TV with wrong EDID. Due to a hardware issue (HDMI cable) the EDID update failed.

004844.563: HDMI1:EDID giving up on reading EDID block 0Run getedid create from SSH, and reboot.
Hmm, I'm using LE 12.0.2 on RPi3B+, and a FullHD Panasonic TV on HDMI-1. The Panasonic TV should offer audio capabilities (ALSA devices), but in your case it doesn't. 
Do you use FullHD resolution for the LE GUI? If not, please try.
A Panasonic TV is not a professional monitor. Try the first HDMI port of the Panasonic TV. I'm using the same TV brand, and it works with my RPi3B+.
Try the same as a remote setup: /storage/.kodi/userdata/keymaps/remote.xml:
Code
<keymap>
<global>
<remote>
<power>shutdown</power>
</remote>
</global>
</keymap>
