Comment 8 for bug 1832998

Just encountered this.

Ubuntu 18.04 server.
Version in repo: pure-ftpd-mysql-1.0.46-1build1

TLS completely broken in this version.

Can confirm that manually installing packages from Ubuntu 19.04 repo fixes issues for me.

```
wget http://mirrors.kernel.org/ubuntu/pool/universe/p/pure-ftpd/pure-ftpd-common_1.0.47-3_all.deb
wget http://mirrors.kernel.org/ubuntu/pool/universe/p/pure-ftpd/pure-ftpd-mysql_1.0.47-3_amd64.deb
dpkg -i pure-ftpd-common_1.0.47-3_all.deb pure-ftpd-mysql_1.0.47-3_amd64.deb
```

TLS now working in Pure-FTPd

```
apt-cache policy pure-ftpd-common
