That day, while setting up another Ubuntu installation, it dawned on me to check whether case-insensitive works for tab completion in Bash? As usual, Google and AskUbuntu did not fail me. Yes, we can do that in Bash. So many years of using Ubuntu and it never occurs for me to raise such question?
To enable case-insensitive, just set completion-ignore-case for the Readline init file, .inputrc.
$ if [ ! -a ~/.inputrc ]; then echo "\$include /etc/inputrc" > ~/.inputrc; fi $ echo "set completion-ignore-case On" >> ~/.inputrc

The final .inputrc file should look like below.
$include /etc/inputrc set completion-ignore-case on set mark-symlinked-directories on
