the following terminal warning. I tried to re-upgrade my system
for many times, but the same thing kept occurring.  the last 4
lines in terminal (during upgrade):  Found Windows 7 (loader) on
/dev/sda1 Skipping Windows 7 (loader) on Wubi system Found
Windows Recovery Environment (loader) on dev/sda2 Skipping
Windows Recovery Environment (loader) on Wubi system   after
these lines, the upgrade is not continuing.  share|improve this
question add comment  1 Answer  These lines appear to be output
from grub setup and are not warnings or errors, can you give
some more lines before or after? What command is being used to
upgrade? and to re - upgrade?  A few times when my upgrade was
interrupted i was able to recover with something like  sudo dpkg
--configure -a  (the correct command should show up when u try
to do apt-get upgrade or apt-get dist-upgrade. More information
can be found here.  share|improve this answer add comment  Your
