Install Zerotier on Kali Linux 2023.2a (problem error while loading shared libraries: libssl.so.1.1)

 1. Uninstall zerotier
    - sudo apt remove zerotier-one -y

2. install again (copy paste script, sudo user)

# save /etc/debian-version
# (which will be something like kali-rolling)
DV_SAVE=$(cat /etc/debian_version)
# pretend we're Debian buster
echo testing | sudo tee /etc/debian_version >/dev/null
# follow ZeroTier install instructions from:
# https://www.zerotier.com/download/
# for example, if you don't care about checking gpg signatures:
curl -s https://install.zerotier.com | sudo bash
# restore /etc/debian-version
echo $DV_SAVE | sudo tee /etc/debian_version >/dev/null

3. DONE
