Can't locate ./acl/md5-lib.pl at /usr/share/webmin/changepass.pl

Ubuntu 20 does not have the correct path of md5-lib.pl in changepass.pl file.

We need to update the correct path there.

You should edit the path in the /usr/share/webmin/changepass.pl at line 6th.

sudo nano /usr/share/webmin/changepass.pl

For Ubuntu use: require "/usr/share/webmin/acl/md5-lib.pl";

For centOS use: require "/usr/libexec/webmin/acl/md5-lib.pl";
