Comment 7 for bug 1808773

My bad, it was installed via the ondrej ppa. I should have noticed that the current versions of libssl is 1.1.0g and not 1.1.1a. I'm sorry for that.

$ apt policy libssl1.1
libssl1.1:
  Installed: 1.1.1a-2+ubuntu18.04.1+deb.sury.org+1
  Candidate: 1.1.1a-2+ubuntu18.04.1+deb.sury.org+1
