@lexmaxak Hello! Thanks for reporting this issue. I could not reproduce this issue on a Ubuntu 22.04 or Debian 11 system. Most likely it's because the command apt-get -yqq install wireguard qrencode failed for some reason when you reinstalled WireGuard, and it's not an issue with the script itself. I'll add a check in the script to help catch this.
