When installing ThinLinc, it's common to "scp -r" the server-cd directory from,
for example, a nightly build. If you later do the same operation again, the
server-cd directory will contain duplicate packages. The installation program
currently does not detect this situation: It says, basically, that "VSM is up to
date and VSM will be upgraded". Also, the installer does not detect if a certain
package is missing.
I think this problem can be fixed quite easily, by modifying glob_relative to
verify that there's exactly one match.
Note that this only happens for development builds as the directories include the version number.
