Hi, Some additional info and the logs attached.
First time when the system boots up , I can see two ubuntus ,on in kernel version 2.x.35 and other one 2.x.32...when I entered on the default ubuntu version 2.x.35 ,then only I faced the above issues.Then I changed to recovery option of ubuntu 2.35 and installed some additional packages and then I can see that network icon is detected.But still I am getting the error for the drive sda1. Also the sound icon is missing in startup applications...hope this info helps...please let me know if any more logs required in this Thanks Sujith S ** Attachment added: "dis-upgrade.tar.gz" https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/658611/+attachment/1686867/+files/dis-upgrade.tar.gz -- Upgrade of ubuntu from 10.04 to 10.10 gives problem https://bugs.launchpad.net/bugs/658611 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
