In Raring, everytime I connect to the network, Cups installs all the printers in the network automatically, some more than once.
Furthermore, I connect a USB printer to the laptop every now and then. Even though the printer is configured already, another printer is added to the list.
I wish to disable this feature and allow only manual installation of printers. How do I go about it?

Both, Ubuntu 12.10 and 13.04 perform very slow when running in VirtualBox 4.2.12.
How do I run Ubuntu with unity or enabled transparency smoothly with VirtualBox?

I can't seem to find a way to customize (add/remove folders/directories) the "Places" menu in the most recent "Files" application of Ubuntu 13.04. The procedures used with "Nautilus" in the previous versions of Ubuntu (bookmarking or drag&drop) don't seem to work anymore.
Does anybody have a clue on how to do that?

I cannot make xmodmap run on login in Ubuntu 13.04. I have searched around, including in askubuntu and all answers I found do not work.
I have a file named .Xmodmap in my home folder which contains the desired mappings. If I run it manually it works fine, so there is no error there. In order to make it run on startup, I have tried:
Using various .xinitrc containing one of the following commands:
xmodmap .Xmodmapxmodmap ~/.Xmodmap /usr/bin/xmodmap /home/NAME/.Xmodmapif [ -s ~/.Xmodmap ]; then
xmodmap ~/.Xmodmap
fi
Using .Xresources instead of .xinitrc with the same variations.
Setting it as a startup application.
None of the above works in Ubuntu 13.04 (64-bit). I also saw a few ideas about globally changing the keyboard mappings, but most of them were not applicable in Ubuntu 13.04 (i.e. the corresponding files did not exist where specified) and I prefer not to touch the global settings anyway.

How to install Haskell Platform for Ubuntu 13.04? I get the following error when I type sudo apt-get install haskell-platform:
E: Unable to locate package haskell-platform error

When using GIT, I have problems with using GIT over SSH, and since it works just fine both from work, and at home with a different modem, it's obviously my home modem that is acting up. I have no problems connecting over HTTP.
So, I'm assuming it is an SSH problem, but I'm no expert at using it directly. Is there any command I can run which sets up a "test" connection, and lets me know exactly when and where along the line the problem occurs?
Pretty much all "larger" commands (such as fetch, clone, or push with much data) from git (even when run with -v) just "hang" in the middle of connecting remotely with no indication as to why they have stopped, so they are of no use.
Is there any way I can get more details on what is happening in the SSH connection?

I post this question since new nautilus is very 'keyboard unfriendly', specially for one-key shortcuts. From 3.4 to 3.6 the very useful 'backspace' shortcut to go to parent directory has gone (along many other features).
In particular I would like to know how to go to the parent directory.

I am installing package RCurl in R and getting an error
checking for curl-config... no
Cannot find curl-config
ERROR: configuration failed for package ‘RCurl’
I have tried to install libcurl on Ubuntu, but it doesn't solve my problem have some dependecies
sudo apt-get install libcurl4-gnutls-dev
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libcurl4-gnutls-dev : Depends: libcurl3-gnutls (= 7.29.0-1ubuntu3.1) but 7.29.0-1ubuntu3.2 is to be installed
Depends: libldap2-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
locate curl config gives me nothing:
locate curl-config
curl-config
The program 'curl-config' can be found in the following packages:
* libcurl4-gnutls-dev
* libcurl4-nss-dev
* libcurl4-openssl-dev
I went through some of the solution RCurl but it is working. Can you suggest or help in this direction. Thank you so much.
Edit
when i tried to install(Curl) from Ubuntu Software center got the same erroe message

This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.

I'm installing Ubuntu 13.04 onto my 32-bit Intel Core 2 Duo CPU, from a live-usb. One of the screens says "Installation type", with the three options "Install Ubuntu alongside Windows Vista" or "Replace Windows Vista with Ubuntu" or "Something else". No matter which of those three options I highlight, the "Continue" button is always grayed out and un-selectable. (I can only select "Quit" or "Back".) (When I highlight the second option, the word "Continue" switches to "Install Now" on the button ... but it is still grayed out and unselectable.)
Other than the fact that I cannot "continue", the installer offers no information about what's going wrong. Any ideas? Thanks in advance!! [I am also happy to hear advice about how exactly I can file a bug report about this.]

I have just updated my HTPC to 13.04 (using do-release-upgrade) and when logging in I get the "new release available" message, while there isn't as I've just upgraded and running that version.
me@mybox: ~$ssh htpc
me@htpc's password:
Welcome to Ubuntu 13.04 (GNU/Linux 3.8.0-19-generic i686)
* Documentation: https://help.ubuntu.com/
New release '13.04' available.
Run 'do-release-upgrade' to upgrade to it.
So I am at 13.04, but I can upgrade to 13.04. Sounds like a plan. Or not.
I have done an apt-get update and upgrade (was nothing new) and rebooted the machine. Why is this message still here, and what needs fixing so it goes away?
For more info maybe:
htpc:~$ uname -a
Linux HTPC 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:19:42 UTC 2013 i686 athlon i686 GNU/Linux
