Mas no Ubuntu 20.04 LTS moderno não é instalável com as seguintes mensagens:
cd ~/Downloads
wget -c https://github.com/lanmessenger/lanmessenger/releases/download/v1.2.37/lmc_1.2.37_x86_64_min.deb
sudo apt-get install ./lmc_1.2.37_x86_64_min.deb

Note, selecting 'lmc' instead of './lmc_1.2.37_x86_64_min.deb'
