comment Unresolvable problem
Hi and welcome to the site. When asking questions, you need to also tell us what you were doing. It looks like this is the error you got when attempting to do something, what was it you were doing? It is also considered nice to actually ask something and not just dump the error message.

comment Passwordless ssh error
@sgp I don't see that. In any case, you can see for yourself. Just cat the authorized_keys file and the id_dsa.pub and you'll see they're completely different. Another thing you can try is to remove the 1st line from your ~/.ssh/known_hosts file. It looks like its trying that key and that might be from an older attempt.

comment Passwordless ssh error
Eeeek! Don't change the permissions! Ever! Nothing will work if you change the permissions on those files. You need id_dsa and authorized_keys to be 600 but id_dsa.pub and config etc. to be 644.

comment Passwordless ssh error
@sgp I don't see why it should work for localhost either. The authorised_keys file is a list of keys that you use to connect to remote servers. Each line has three fields: the key type, the public key and the user@host information. The file you are adding to it has a completely different format and, more importantly, is the private key, not the public one. Anyway, try again and use your normal password, that's the one it's asking you for.

comment Passwordless ssh error
@sgp what are you trying to connect to? Your approach might, though I doubt it since the format of the files is wrong, work for localhost but not for any other.

comment Passwordless ssh error
@sgp sure you do. It's your password for the machine you're trying to connect to. If you don't have one, then you don't have access to the target machine and, obviously, you can't set up passwordless access.

comment How to add and pass system password as a variable in a script
But why would you need to validate the password? I don't understand. Why even write a script at all? Why not just use shutdown directly? And why validate? Just run the command, if the error complains about the password, then you had the wrong password!

I wasn't asking anything :) I just saw this meta post.

comment How to add and pass system password as a variable in a script
System password for what user? Setting aside the obvious security issue (you really don't want to have passwords written in plain text in a script), we can't tell you how to check a password unless you tell us what this password is supposed to unlock!

comment 'libstdc++.so.6: cannot open shared object file: No such file or directory"
@Fabby the OP is trying to use the android debugger on Ubuntu. The error is about a library missing from Ubuntu, the solution posted below involves installing the missing library, once more, on Ubuntu :).

comment 'libstdc++.so.6: cannot open shared object file: No such file or directory"
Why did you vote to close this? As far as I can tell, and as suggested by your solution, this is an Ubuntu issue and not Android.

comment Blocking Start of Terminal
@imallett yes, this approach could fail if you force close the terminal before the process is finished. What I don't understand is why in the world you need a terminal in the first place? Why not just run the commands you need to run by themselves? Why do you need to open 2 separate terminals? I get the feeling this might be an XY problem.

comment “STOP error reading namelist input_data in subroutine strtup” Linux Terminal
What code? What input file? How are you running this code? What is it supposed to be doing? Please edit your question and add more details (especially the code you're running, the command you use to run it and the input you give it). How can we help if you don't even tell us what you're doing?

comment How to change display's position from command line?
Please edit your question and add the output of xrandr. Also, please explain what you need. Are you expecting one screen to be above the other? By how much? Do you just need one screen to be on the right of the other one?

comment Windows 8 safemode from grub
This is more about the Windows than the Ubuntu side of things. You would get better answers (and this would be on topic) on Super User.

comment How to redirect stderr to a file
@AndréM.Faria yes. But the last two commands are equivalent, they will send both error and output to the same file.

comment I Have 2 Ubuntu options in Bios even after uninstalling the partition of elementary os freya in windows?
Please edit your question and clarify your situation. Do you have an Ubuntu installation on the machine? Can you boot into Linux? Also, you don't set the BIOS to boot an OS, are you talking about the boot loader? Which one? Windows' or GRUB?

comment Permission denied (failed to create pid) when starting SphinxSearch
Are you suggesting that the OP change the permissions of /var/run?
