xmllint: command not found

[hub2git]

Hi there.
Running Linux Mint Cinnamon 21.3 Virginia.

I've just installed chbrown's overdrive by doing this:
mkdir -p ~/.local/bin
curl https://chbrown.github.io/overdrive/overdrive.sh -o ~/.local/bin/overdrive
chmod +x ~/.local/bin/overdrive

I then tried to download an overdrive audiobook:
overdrive download AudiobookTitle.odm
Cannot locate required executable "xmllint". This will likely result in an error later on, which might leave you in an inconsistent failure state, but continuing anyway.

I installed libxml2-utils in Synaptic package manager and now it works.
