What PHP version are you running?

Try downgrading the PHP to 7.1 or install XF version 1.5.19, alternatively there was a bug that was fixed in 1.5.19, you could manually edit a file.

In the file src/XF/Install/Upgrade/2000010-200a.php you will find this line:

$permissionCache = @unserialize($admin['permission_cache']);

I believe all that's required is to change it to:

$permissionCache = @unserialize($admin['permission_cache']) ?: [];

And then hit refresh and the process should continue.

I've created a bug report for this as that manual edit solution relates to a bug from upgrading to XF2, not installing XF1 on PHP 7.2:
