Upgrade to Ubuntu 20.04

There are issues using a GUI to upgrade, sometimes you cannot get to an acceptance button or the like. It's better to just upgrade from the terminal itself.

Refer: https://ubuntu.com/blog/how-to-upgrade-from-ubuntu-18-04-lts-to-20-04-lts-today

Use the following to see if an upgrade is available

sudo do-release-upgrade -c

Perform the actual upgrade

sudo do-release-upgrade

DVD Playback with Ubuntu 21.04
Refer: https://linuxconfig.org/unable-to-play-the-file-missing-decoder-on-ubuntu-20-04-lts-focal-fossa

PLEASE NOTE: VLC is still a better player option

sudo apt install -y ubuntu-restricted-extras
sudo apt install -y libdvdnav4 libdvd-pkg gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly

Desktop Icons No Longer work with Nautilus

Refer: https://markperez.dev/blog/organize-desktop-icons-ubuntu/

You will need to make Nemo your default desktop controller

Disable Nautilus desktop

gsettings set org.gnome.desktop.background show-desktop-icons false

Install the software and remove gnome extension

sudo apt install nemo dconf-editor ; sudo apt remove gnome-shell-extension-desktop-icons

Autostart the nemo desktop icons, but this needs added as startup action:

nemo-desktop

Then in UI GUI "Startup Applications", add

Name: nemo-desktop
Command: nemo-desktop
Comment: Get icons working on Desktop

Reboot, to complete Desktop setup

Charles did NOT upgrade

Remove it

sudo apt-get remove charles-proxy

Refer: https://www.charlesproxy.com/latest-release/download.do

Extract the download, and launch

/home/mruckman/Downloads/charles/bin/charles

The following DOES NOT Work!

wget -q -O - https://www.charlesproxy.com/packages/apt/PublicKey | sudo apt-key add -
sudo apt-get update
sudo apt-get install charles-proxy

Stacer needed re-installed, use software center

Update How Visual Studio Code Works

Remove all parts of "Visual Studio Code"

sudo apt purge code
sudo apt autoremove

Delete launchers

/usr/share/applications
~/.local/share/applications

Visual Studio Code is going to have problems, ended up removing references to it from menu editor.

Refer: https://github.com/microsoft/vscode/issues/41037

sudo apt-get install code

You need to delete this file and create a new one with menu editor.

/home/mruckman/.local/share/applications

[Desktop Entry]
Version=1.1
Type=Application
Name=Visual Studio Code
Comment=Editor
Icon=com.visualstudio.code
Exec=/usr/share/code/code --no-sandbox --unity-launch %F
Actions=
Categories=Development;

You can use this file instead of creating it:

menulibre-visual-studio-code.desktop
