Bug Description
This bug report notes the same problems described in bugs 1161771 and 1130381, but is filed separately to make it clear it also applies to the lastest 64 bit LTS server release. Likely, it applies to other releases as well.
In the ISO named ubuntu-
http://
these 29 files have all had both their extensions truncated to 3 characters and their root names (not counting leading path names) truncated to 61 characters. So counting the "dot" character, they have all had their base file names trimmed to a total of 65 characters:

Before someone suggests that the ISO is fine and that the filenames must have been clobbered by whatever tool I was using to examine the ISO file, know that the ISO file has independently been examined by windows 8 file explorer, zip7, Windows ISO Mounter, and WinRAR and they all show these same truncated file names.
So what you say? Is this really a problem? I'm guessing it must NOT be a problem for normal CD-based installations (perhaps CD drivers expect long file names to be shortened???) or you would have had too many complaints to be ignroed, but for my USB installations these clobbrered names are causing much grief. I have attempted to build an installation flash drive with this ISO using both LiLi USB Creator and unetbootin-
There was a problem reading data from the CD-ROM. Please make sure it is in the drive. If retrying does not work, you should check the integrity of your CD-ROM.
Failed to copy file from CD-ROM. Retry?
Once I realized what the problem was (which took me an entire day), I modified all of the file names above so they all consistently ended with the string "precise1_
You say maybe my USB drivers are just finicky? They are asking too much to expect the encoded filenames to match the requested filenames! Well, there have been at least two others that have taken the effort to submit bug reports documenting this same problem (as noted above). One was closed as invalid. The other was simply ignored and timed out. In addition, there are countless forum posts where people have documented and discussed this same problem. Here are just a few:

This "Official" Ubuntu documentation tells people you can install Ubuntu from a flash drive and list LiLi and unetbootin-windows as tools to create the bootable flash drive from windows:

But it doesn't work.
Thanks for reading.

I just took the ISO file in question and mounted it directly on an ubuntu system. Much to my chagrin, the file names in the ISO do actually appear to be good. But this means that at least 6 different windows applications all showed the same truncated filenames.
In any case, there still seems to be some fundamental problem with the windows-based flash-drive creation process used by both LiLIi and unetbootin-windows. Is there ANY windows-based mechanism for creating a bootable ubuntu flash drive that successfully preserves the long filenames?
Sorry for my false claims.
