[Bug 1283240] [NEW] Corrupted filenames in ISO Ubuntu 12.04.4 Server amd64

Fri Feb 21 21:08:59 UTC 2014

Public bug reported:

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-12.04.4-server-amd64.iso downloaded from this
URL:

                  http://www.ubuntu.com/download/server

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-
windows-585.exe.  With both tools, the USB copies these files along with
their truncated names perfectly.  No surprise there.   But attempting to
install from such a USB results in the following error while loading
installer components:

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_amd64.udeb" and then everything worked.

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.
