I am using Ubuntu 10.10 Maverick Meerkat and have getdeb (playdeb) repository for Lucid Lynx. Lucid repo can be added to Maverick and many applications can be installed without problems. However, I got this error while trying to install a game called 0ad.
0ad:
Depends: binutils (<2.20.2) but 2.20.51.20100710-1ubuntu2 is to be installed
I could downgrade my binutils to an appropriate version by downloading deb from somewhere else and that would be the ideal thing to do if it did not break any packages, but I decided not to as it could break other packages and decided to try out something that is never recommended and should not be done if you don’t know what you are doing. You should know that this could also lead to broken packages but fortunately this only breaks a game (that is what I am going to install) at worst and not some system program. I just changed the dependency to the version that I had by editing the package description. To do so, I needed to open the file /var/lib/apt/lists/archive.getdeb.net_ubuntu_dists_lucid-getdeb_games_binary-amd64_Packages as root by running
gksu gedit /var/lib/apt/lists/archive.getdeb.net_ubuntu_dists_lucid-getdeb_games_binary-amd64_Packages
If you are using 32-bit version of Ubuntu, you should probably try something else.
The package description for 0ad looks like the following:

In short, it is a war/economy strategy game allowing you to recreate or rewrite the ancient history of western civilisations.
I changed the line in the “Depends” from binutils (<< 2.20.2) to binutils (<< 2.20.52) and restarted synaptic package manager. Then I could download the game without problems. But it shows dependency errors and the game can’t be configured. So, I removed it from Synaptic. Then what I do next is copy the 0ad deb file to my desktop; mine is called 0ad_0.0.0+r07539~pre-alpha-1~getdeb1_amd64.deb and it is in /var/cache/apt/archives/. So, I fire up the terminal and do the following:
sudo cp /var/cache/apt/archives/0ad_0.0.0+r07539~pre-alpha-1~getdeb1_amd64.deb /home/[USERNAME]/Desktop/
where [USERNAME] is my username. Now the game is copied onto my desktop. Now I changed the owner to myself, so that I can read it:
sudo chown [USERNAME] /home/[USERNAME]/Desktop/0ad_0.0.0+r07539~pre-alpha-1~getdeb1_amd64.deb
Then, I needed to edit the control file and repack the deb. To do so, I just extracted it:
cd ~/Desktop mkdir -p extract/DEBIAN dpkg-deb -x 0ad_0.0.0+r07539~pre-alpha-1~getdeb1_amd64.deb extract/ dpkg-deb -e 0ad_0.0.0+r07539~pre-alpha-1~getdeb1_amd64.deb extract/DEBIAN/
Then, I edited the control file:
cd extract/DEBIAN nano control
and changed the file to say binutils (<< 2.20.52) instead of binutils (<< 2.20.2). Just Ctrl+O followed by ENTER to write the changes and Ctrx+X to exit nano.
Then, I just went back to the Desktop folder.
cd ../../
Then I repackaged the deb file:
mkdir build dpkg-deb -b extract/ build/
Then, I could find the new deb inside the build folder in the Desktop which I can install without problems. After it is installed, I tried to launch it from the terminal (0ad) but I got an error saying:
./pyrogenesis: error while loading shared libraries: libbfd-2.20.1-system.20100303.so: cannot open shared object file: No such file or directory
So, it really needs the binutils version it says it does. Anyways, just creating a symbolic link named libbfd-2.20.1-system.20100303.so in /usr/lib to the version that I have i.e. libbfd-2.20.1-system.20100303.so did it for me. To do so, in terminal I typed the following:
sudo ln -s /usr/lib/libbfd-2.20.51-system.20100710.so /usr/lib/libbfd-2.20.1-system.20100303.so
Hope this helps.
