Switched to a different computer; Dell Precision T5600
Ubuntu 20.04 daily build April 1, 2020
installed Ubuntu 20.04 daily build (dated 4-1-2020) noticed some changes/additions to look and feel from previous versions.
When booting up from the flash drive, it went to a black screen/white text and some kind of disk check display %xy completed;
Then after install and reboot, it goes to the black screen with white text - remove the install media and press enter; this is different, as well as some changes to the theme/desktop colors;

Initial things I noticed:
Also, the printer auto-discovery is engaged and flashing different printers it finds; see below.
Software Updater prompts to install updates; installed these updates, not many just some docs.

1) Configure ssh to allow ssh logins from remote hosts to this host; when trying from remote to this host, get error msg: ssh: connect to host <somehostname> port 22: Connection refused
2) From past experience, just need to install this package "openssh-server" package; this will allow ssh connections.
$ sudo apt-get install openssh-server

Printer auto-discovery situation; it annoys me that every time I boot up/login I see the several pop-up messages stating that this or that network printer has been added. It would be so nice if this could be configured away. (As of this writing, I haven't figured out how to stop these network printers discovered)
I found a google search procedure for this and tried it on an earlier daily-build; it seemed to work to stop the pop-up messages, but on this computer/OS build, it happens every time I arrive at the login screen. Sigh!!
But I still copy the "system-config-printer.desktop" icon from /usr/share/applications folder to my desktop (right-click the icon, copy to the
desktop, then right-click the icon on the desktop, and select "allow
launching" and now I can start the printer app I'm used to seeing and
using. For now, I'm just ignoring the pop-up messages.=-=-=-=-=-=-=-=-=-=

install youtube-dl;
I have used youtube-dl for several years now and it works for me when I need to have a local copy of a youtube video. Here's the process I follow.
$ sudo apt install curl
$ sudo curl -L https://yt-dl.org/downloads/latest/youtube-dl -o /usr/local/bin/youtube-dl
$ sudo chmod a+rx /usr/local/bin/youtube-dl
$ sudo ln -s /usr/bin/python3 /usr/local/bin/python
Now you can open youtube.com in browser and search for the video of your choice; when you open the page of the video to download, in this example, the video URL is: https://www.youtube.com/watch?v=U3XPzwjhSZw
(one of my favorites-"Oye Como Va")
open terminal and cd to the folder of your choice; enter this command to see which available video is the 'best':
$ youtube-dl -F https://www.youtube.com/watch?v=U3XPzwjhSZw
(the output shows that #18 is the 'best version' to download)
<snip>
18 mp4 360x360 360p 290k , avc1.42001E, mp4a.40.2@ 96k (44100Hz), 8.90MiB (best)
Modify the cmdline to include the number of the 'best' video:
$ youtube-dl -f 18 https://www.youtube.com/watch?v=U3XPzwjhSZw
[youtube] U3XPzwjhSZw: Downloading webpage
[download] Destination: Oye Como Va-U3XPzwjhSZw.mp4
[download] 100% of 8.90MiB in 00:00
NOTE: don't forget the difference of the -F (capital F) vs the 2nd cmdline -f (lower case f).
Then open this mp4 video in the default Videos or VLC (which I always d/l and use.

install vlc (not included in default ubuntu 20.04 install); open ubuntu software, (takes a while as it says it is downloading the catalog), then search for vlc and install. This is my favorite media player.

Ripping CD's to mp3/oog/flac files
The default media player on Ubuntu 20.04 appears to be Rhythmbox.
Insert CD into player (I know; old school; but I have a lot of CDs and I'm kinda retro myself, ie old!))
Open RB; see the CD title under the "Devices" category; you should see all of the songs and titles; NOTE: I notice that sometimes the CD title lookup does not find the info for the CD; so I sometimes create a win10 VM using virtualbox and use the default windows media player, which has always worked.
If the menu bar is not visible, click on the triple dot ... pattern and it should appear. Extract; you change the ripped format in the preferences area, flac, oog, mp3, mp4 audio.
I noticed that if I selected the mp4 audio format, that when I clicked "Extract" the rb player would crash, exit and prompt to report the crash; flac is working though and oog; but seems slow to me. Windows media player is faster in a win10 VM under virtualbox.
