Since the version of Ubuntu used in the "TRES"
version of pubuntu is no longer supported
by Ubuntu, I Have built a version that was
upgraded to Ubuntu 10.4 LTS(long term support).
There were numberous problems after the
upgrade. The fixes included are:
* Version 4 slimLZM2 U10.4
- Compressed with 7-zip Ultimate compression
method, LZM2 algorithm
- Ubuntu 10.4.3 LTS (Lucid Lynx)
- COlinux 0.7.9 (kernel 188.8.131.52-co-0.7.9
stable release 2/16/11)
- root filesystem about 3.5gb
- Cygwin, Cygwin/X 1.7
- console keyboard configured for USA layout.
- Ubuntu Screensaver disabled to prevent
X server from going into a CPU loop.
- Fixed Plymouth aborts by mounting /dev as
tmpfs in fstab
- Fixed Xauth bad command by stripping
screen number in display variable(.profile)
and added entries for colinux gateway
- Fixed missing console output and gnome panel
with disabled shutdown button by disabling
- Added sym link for dos2unix to fromdos
(needed by postmount_pubuntu.sh)
- run postmount_pubuntu.sh under bash to
avoid "- e" being added to fstab.
- Note: readahead exit status 4 can be ignored
(due to mount points not required for the
- Disable screen clear on console (TTY1) so
- Remove Office software, games, and reduce
free space on root to approximately 10%
to reduce transfer time of compressed
I am making this release available for others
to use in files section of this Project.
The names of the Files are:
You can use a utility like MD5SUM or
HASHCALC to verify that all of the file got
downloaded correctly (the .md5 file above
contains the hash for the .exe file). If all
the files are in the same directory you can
use the following command line:
md5sum -c Portable_Ubuntu_V4_081411.md5
It should print "OK" if the file is correctly
downloaded. It is STRONGLY RECOMMENDED that
you do NOT skip this verification step as the
probability of a transmission error is higher
with large file downloads.
Run the .EXE file by double clicking on it
and it will ask where you want to put the
decompressed files. After all the files are
decompressed you can run portable Ubuntu by
double clicking on the pubuntu.exe file in
top level directory that the files were
The configuration file still has the memory
specified as 254 and was tested to run on
a Pentium 4 with 1gb of memory. You may
want to increase the memory size is you have
more available. Also, the keyboard was set
to the US layout for the console. If you
need a different layout, using the following
command in the console window:
sudo dpkg-reconfigure console-setup
Also, the ubuntu screen saver has been
deactivated to prevent the X-windows server
from going into a CPU loop. Windows has its
own screensaver, so there is no need to have
more than one screensaver active.
I believe that most of the problems reported
on the previous version are fixed in this
version (V4). If you find any that are not,
please report it. If you have problems with
the installation of pubuntu V4 report them
in the forum. If you have problems with
Ubuntu check the Ubuntu forums before
reporting it here. If you have problems with
Colinux, check the Colinux mailing list or
wiki before reporting it here.
Note: the .exe file scanned for viruses with
Kaspersky 2012 and is free of any viruses.
My testing indicates that it takes about 3
hours to download from sourceforge and about
20 minutes to decompress the distribution.
Note: you may want to install office software
after decompressing as it removed to make the
distribution smaller. Before installing
additional software it may need to expand the
root image/partition. You may use the
toporesize utility "tfile" on windows to
expand the container:
tfile device:\...\images\rootfs.img new_size
new_size is in megabytes. Then boot pubuntu and
run resize2fs to expand the file system to fill
the full partition. Consult the help forum for
a more detail description of the process of
expanding the root image.
