gimp: error while loading shared libraries: libgegl-0.0.so.0: cannot open shared object file: No such file or directory

After upgrading from Ubuntu 11.10 to 12.04 I found gimp couldn’t access the shared libraries it needed, most likely an error with symbolic links as described by lovelyindia in this post.

Fix 1:

He managed to fix the issue by removing gimp and purging the offending libraries and then letting apt deal with the libraries when he re-installed gimp, as per the below commands:

sudo apt-get update 
sudo apt-get purge gimp libgegl* libbabl* 
sudo apt-get install gimp 
sudo apt-get clean

While this is likely to work for most people encountering this issue, it didn’t for me.

Fix 2:

Then I remembered I had used the repogen source list generator, in which I chose to include the gimp svn build. While you may not have gone about it the same way, you may also have a different repository in your sources.list file which is causing this issue, if the previous method did not resolve the issue.

In order to fix this, I had to open the sources.list file and comment out the offending repo.

sudo gedit /etc/apt/sources.list

Now search for any reference to gimp, in my case this was the lines I changed:

#### Gimp SVN - https://launchpad.net/~matthaeus123/+archive/mrw-gimp-svn
## Run this command: sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 405A15CB
deb http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu precise main

I commented out the line linking to the repo by adding a ‘#’ to the front, as below:

#### Gimp SVN - https://launchpad.net/~matthaeus123/+archive/mrw-gimp-svn
## Run this command: sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 405A15CB
# deb http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu precise main

I then uninstalled gimp, once I knew it may have been the newly added repository that I had added:

sudo apt-get purge gimp

Then I saved and exited the file and updated apt:

sudo apt-get update

I then re-installed gimp:

sudo apt-get install gimp

This solved the issue for me, I hope this helps!

Ubuntu 11.10 Proxy Settings

Temporary proxy:

Where proxy.addr is the proxy address, 4040 is the port number. Some proxies may require “http://” before the address.

export http_proxy="proxy.addr:4040"
export ftp_proxy="proxy.addr:4040"
export https_proxy="proxy.addr:4040"

If you run this in a terminal, any programs opened from that terminal will adhere to the proxy you set but any other applications will not. This makes it useful if you just want to launch a browser for a quick browsing session but don’t need the whole system to access the internet.

If you do need your entire system to access the network, you can add these to the bottom of “~/.bashrc” this will enable any new programs running and the whole system (after a restart) to use the settings. Essentially ~/.bashrc are commands run when a terminal is opened.

NOTE: If you do this, when you remove them your machine will likely need a restart to undo the changes.


Proxy with login

If your proxy server requires a login, this is an addition of the above however the syntax is as follows:

user:pass@proxy.addr:4040

APT Proxy:

APT (used for system updates) has its own proxy settings, which seem to ignore the above settings.

Where nano is the editor, if you prefer use a graphical one such as gedit, kedit etc.

sudo nano /etc/apt/apt.conf.d/02proxy

add:

Acquire::http::Proxy "http://proxy.addr:4040";

The list of sources could not be read – Ubuntu

E: Type ā€˜nā€™ is not known on line 2 in source list /etc/apt/sources.list.d/bean123ch-burg-lucid.list

E: The list of sources could not be read.

To fix this or similar errors open the file, for example “/etc/apt/sources.list.d/bean123ch-burg-lucid.list” and check for rouge characters. In this case there was new line with the letter ‘n’ in place, removing it solved the issue. Make sure to run “sudo apt-get update” to refresh the sources and everything should be fixed. I was also unable to see any software in the “Ubuntu Software Center” because of this.
