Pysdm causing boot issues

[lostwilight]

Hi, I am a fairly new user of Ubuntu, or any Linux OS for that matter.

Recently installed Pysdm in hopes of automounting my other partition.

However, after a reboot, I am unable to boot properly into Ubuntu.

Errors given would be similar to those posted on
http://ubuntuforums.org/showpost.php?p=8376434&postcount=4

The same errors would occur even if I started recovery mode.

I would like to know if there is any way of stopping pysdm from starting up or if there is any way of solving this issue.


Update: Uninstalling pysdm through apt-get remove pysdm did not help. The same error still occurred upon startup.

well if you uninstalled pysdm then pysdm may not be your problem.
Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and use the link in my signature to download the Boot Info Script to the desktop. Once on desktop open a terminal (Applications > Accessories > Terminal) and run this command
sudo bash ~/Desktop/boot_info_script*.sh This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

Thanks for the reply.
Here is the requested output.

I had faced similar problem one year back when after installing pysdm I mistakenly blocked the Home partition and it failed to boot everytime. Even several reinstalling Ubuntu from the scratch didn't help and it was failing to boot everytime.
Finally I had to change the permission for my Home Partition to get it work. Though I don't remember the command but hope somebody comes up with this solution.

This was my case and yours could be different. So, all the best.

Note the red in yours. mine says errors=remount-ro 0 1

I would boot the Live CD and mount your Ubuntu (not the Live Cd's) root filesystem. You can mount it by going Places > Computer and highlighting that partition/device on the left pane of the file browser. Once you see the directories on right of file browser it is mounted. Now open a terminal and run
gksu nautilus

Navigate to the Ubuntu root partition in this new root browser. Navigate to /etc/fstab. Open fstab and make the changesabove to yours. Click Save on the toolbar and close file. Reboot without Live CD and see if Ubuntu boots now.

Thanks for the help.

After following your instructions,
I am now able to successfully log into my own account.

You're a life saver. :P

You are welcome, but without the results of the boot info script I or anyone else would probably have never saw the problem. I would run the script again now that your machine is booting and study the contents of that RESULTS.txt file. You will learn as lot about your current setup and boot process. It is an indispensible tool for boot/partition problems. Once you understand your machine's setup and boot process as reported in the RESULTS.txt file you will have insight to help others with their problems.
