Change {page} to the page number. It's indexed at 1, so -f 1 would be the first page.

Lubuntu 20.04 Writer Spell Checker NOT Working

Refer: https://askubuntu.com/questions/1150144/spell-checker-not-working-in-libre-office-6-0

File: dict-en-20200601.7z

This worked for me. Even hunspell or myspell, as suggested by resplin, didn't work.

However adding this extension to Libre Office worked like charm: https://extensions.libreoffice.org/extensions/english-dictionaries/

You'll need to go to Tools > Extension Manager > Add > {upload extension file}. Restart.

Install IntelliJ on Ubuntu

Refer: https://www.jetbrains.com/help/idea/installation-guide.html#

Install the Toolbox App or use Snap instead

Download the tarball .tar.gz from the Toolbox App web page.

Refer: https://www.jetbrains.com/toolbox/app/

Extract the tarball to a directory that supports file execution.

For example, to extract it to the recommended /opt directory, run the following command:

$ sudo tar -xzf jetbrains-toolbox-1.13.4801.tar.gz -C /opt

Execute the jetbrains-toolbox binary from the extracted directory to run the Toolbox App and select which product and version you want to install. After you run the Toolbox App for the first time, it will automatically add the Toolbox App icon to the main menu.

$ sudo snap install intellij-idea-ultimate --classic
$ sudo snap install intellij-idea-community --classic

Refer: https://www.jetbrains.com/help/idea/uninstall.html#

$ sudo snap remove intellij-idea-ultimate
$ sudo snap remove intellij-idea-community

Docker with VPN

Did NOT work with Ubuntu 20.04 installation

There's a setting with Cisco AnyConnect to "Allow local (LAN) access when using VPN (if configured)

Refer: https://www.lullabot.com/articles/fixing-docker-and-vpn-ip-address-conflicts (pdf)

By default Cisco AnyConnect was interfering with Docker running on localhost.  The fix was to have Docker use a different range of IP addresses.

$ sudo nano /etc/docker/daemon.json

daemon.json

And the restart your computer.
