Can someone explain why users syslog and uml-net have /home in /etc/passwd, even though these directories in /home don't actually exist?
cat /etc/passwd
root:x:0:0:root:/root:/bin/bash
syslog:x:101:104::/home/syslog:/bin/false
...
uml-net:x:107:111::/home/uml-net:/bin/false
...
I am running 12.04.
I read this https://askubuntu.com/a/90219/18876 as reference.
I checked all the one I have.

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-image-generic-pae : Depends: linux-image-3.2.0-40-generic-pae but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
Now I don't know how to proceed, especially I don't want to mess up the computer. Ideas? Thanks.
Solution
I found My /boot partition hit 100% and now I can't upgrade. Can't remove old kernels to make room later. Basically, I followed his advise by [removing] old vmlinuz initrd, abi and System.map files individually until I got enough free space. I only need to delete the first two.
Then I do sudo apt-get install -f and finally use @Salem's little bash script to remove most of the old kernels. I kept the last two as suggested. Reboot at the end, and then if I do uname -a I will see the new kernel is now installed (in my case, that's 40).
For example, I can use ssh-id-copy to get the key and login to the remote server without entering the password.
Is there a similar mechanism to run as root without prompting password?
I don't know. If login with a key is sort of safe, then I argue there should be a mechanism like that for sudo. NOPASSWD is not a good solution, however.
Thanks.
The method export vname=value will override the original value. I want a way to append to the old value by colon.
Any idea how? Thanks.
I am installing Vagrant manually with the deb.
I did sudo dpkg -i vagrant.....deb and I found it's in /opt/.
Basically it doesn't add to the bash profile like apt-get does.
Is that supposed to happen with dpkg?
Thanks
I have an assignment to write PHP code, and upload the data to our school student's account. To make sure my script is working, I need to change the permissions on the files.
I am not a root because I am a student. How can I fix that problem?
chown: changing permissions of `nyccrash.txt': Operation not permitted
Those files has permission labeled as apache
The owner and user are apache, according to ls -ls
Thanks.
I run a web app in one of my lab servers, and I have already setup X11 Forwarding on those machines. Other lab members can tunnel through SSH, and browse that web app on their local browser at home.
I can't. Last time I checked with them, there is almost nothing I need to do.
When I type 192.168.1.113/webapp I get nothing.
Any tips?
THanks.
I ended up using the second method :)
ssh -L 8080:<server-ip-address>:80 <username>@<remote-addr> -N
I don't have admin privilege on this Ubuntu machine, and I don't see a way to build Terminator. I found the tar.gz which contains setup.py but that is not what I want.
Can someone please guide me? Thank you.
I don't have fancy directory seperation. I have a desktop and laptop, and for the last few months I did a lot of work on my laptop. I don't want to waste my time installing and configuring on my desktop.
Can I use the laptop's backup on the Desktop?
I know the potential concerns are drivers. How can I deal with such issue? (Both are Ubuntu 11.04)
Thanks.
I have been looking into this - but I can't get previous entered commands in Terminator (multi-terminal). I have looked into the Preference but I don't see how it is done.
I know this is not really Ubuntu question, but I am sure many of you have used Terminator.
Does anyone know how to get the previous entered commands?
Thanks!
