openconnect: symbol lookup error: /lib/x86_64-linux-gnu/libxmlsec1.so.1: undefined symbol: xmlIOFTPRead, version LIBXML2_2.4.30

I have installed openconnect by:

sudo apt install openconnect

Then I'm calling it by:

echo MyPassword | openconnect --pfs mydomain.com:8442 -u MyUsername

But the following error is thrown:

openconnect: symbol lookup error: /lib/x86_64-linux-gnu/libxmlsec1.so.1: undefined symbol: xmlIOFTPRead, version LIBXML2_2.4.30

Does anyone have any idea why this is happening?
