You can not use setup from the command line to upgrade to a different version
format: Cygwin currently has no way to specify a package version on the command
line like apt ... pkg=ver. You will just get the same messages and problems as

You must download and run Setup interactively.
On the Select Packages panel, change View to |Full| or |Up To Date|;
in Search enter |liblz4|;
on each package line under column New, click until the version to be installed
reads 1.7.5-1;
click the [Clear] button;
change View to |Pending| to verify the version;
then click [Next] to upgrade.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
