Is it possible to install lanmessenger on Ubuntu 20.04 LTS?

On previous Ubuntu versions like 18.04 LTS I was able to install LAN Messenger.

But on modern Ubuntu 20.04 LTS it is not installable with the following messages:

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

This happens because of an issue with old libssl1.0.0 package, but LAN Messenger is installable with below workaround:

cd ~/Downloads
wget -c https://github.com/lanmessenger/lanmessenger/releases/download/v1.2.37/lmc_1.2.37_x86_64_min.deb
wget -c http://archive.ubuntu.com/ubuntu/pool/main/o/openssl1.0/libssl1.0.0_1.0.2n-1ubuntu5.7_amd64.deb

sudo apt-get install ./libssl1.0.0_1.0.2n-1ubuntu5.7_amd64.deb
sudo apt-get install libqt5multimedia5

sudo apt-get install ./lmc_1.2.37_x86_64_min.deb

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
