Yes, again, except this time they didn't bother re-fixing it for the final release. Since people will probably run into this, I'm raising this as a tracker bug for https://bugs.launchpad.net/ubuntu/+source/lsb/+bug/798192. If nothing is done about this shortly then we may have to add something to Platform Specific Notes.
Platform specific notes updated in r26053. I have also removed the recommendation of installing an alternative desktop, since XFCE is simply broken and (unless they fix the LSB bug) ThinLinc needs to be somewhat shoe-horned onto this platform regardless of which DE is used. Recommend installing on 12.04 instead. Closing.
Platform specific notes are somewhat unclear about how to fix the issue, first of lsb-core is installed with tl-setup and therefor the suggestion to patch the files "before installing" will fail, and we should be clearer that it is tl-setup that fails, and when it does, one can perform the "patching" and rerun tl-setup a second time to carry out the setup of ThinLinc.
Fixed in r26117.
