I think that v2.12.3 is the package in the ubuntu repository. If so, you don't need to uninstall it, because it's installed in /usr/bin, while the packages provided by lilypond.org are installed either in your home or in /usr/local (if you install it as root). There will be no conflict.
However, if you want to uninstall v2.12.3 you can use Synaptic or type in a terminal: sudo apt-get remove lilypond The error belows is weird. Enter in Downloads and type: ls -l You can try also the "graphical way". Use the file manager to reach the directory, right click on the .sh file and choose properties. In the Permissions tab (or something like that) you must check Execution. Close and clic normally on the file. You'll see a window asking if you want to see the file or run it. Tell him to run as a program and everything should work. Unless the downloaded file is corrupted. Post the ls -l command 2011/6/10 MING TSANG <tsan...@rogers.com> > Thank you Helge Hafting, Janek Warchol, Federico Bruni for helping me to > use terminal commands in ubuntu. > > I downloaded the right file - dir shows it. > Now I copied the error - see below: > > <><><><><> > tsang@tsang-HP-Pavilion-dv2000-EZ723UA-ABL:~$ dir > acl Downloads Public Test.pdf yming.xhb~ > BOOKS Dropbox rosegarden Test.ps your-love.ly > Calibre\ Library examples.desktop Templates untitled.xhb > Desktop Music Test.ly Videos > Documents Pictures Test.ly~ yming.xhb > tsang@tsang-HP-Pavilion-dv2000-EZ723UA-ABL:~$ cd Downloads > tsang@tsang-HP-Pavilion-dv2000-EZ723UA-ABL:~/Downloads$ dir > 2011_summer_camp_headcount_May24.xlsx libflashplayer.so > gsview-4.9 lilypond-2.13.61-1.linux-x86.sh > gsview-4.9.tar.gz lilypond-2.14.0-1.linux-x86.sh > install_flash_player_10_linux.tar.gz usr > tsang@tsang-HP-Pavilion-dv2000-EZ723UA-ABL:~/Downloads$ sh > lilypond-2.14.0-linux-x86.sh > sh: Can't open lilypond-2.14.0-linux-x86.sh > tsang@tsang-HP-Pavilion-dv2000-EZ723UA-ABL:~/Downloads$ > <><><><><> end of message > > QUESTION: > Do I need to uninstall v2.12.3 lilypond?
