I need to install lipng12-0 on ubuntu 22.04 to make an old Canon printer work.

On 20.04, I followed the instructions given here : How to correctly install libpng12-0 on the Ubuntu 19.10?

But it seems to no longer work for ubuntu 22.04.

Any ideas to make it work on ubuntu 22.04 ?

I am in the same boat as you. I recommend compiling from scratch given the source code in the PPA. Basically, this should do what you want it to do. It installs essential packages to build, makes a source folder, gets the source, extracts the source, configures the build environment, builds the library, installs the library and set up the necessary symlinks in /usr/lib.

sudo apt install build-essential zlib1g-dev
cd
mkdir src
wget https://ppa.launchpadcontent.net/linuxuprising/libpng12/ubuntu/pool/main/libp/libpng/libpng_1.2.54.orig.tar.xz
tar Jxfv libpng_1.2.54.orig.tar.xz
cd libpng-1.2.54
./configure
make
sudo make install
sudo ln -s /usr/local/lib/libpng12.so.0.54.0 /usr/lib/libpng12.so
sudo ln -s /usr/local/lib/libpng12.so.0.54.0 /usr/lib/libpng12.so.0

Hopefully this helps you get that legacy app running. Good luck!

I use a Canon Pixma 8250/8200 Series with Ubuntu 22.04.

Like Archisman Panigrahi mentioned in a comment above, the solution from user1083006 works for me and is very easy:

For Canon Pixma MG4250 and other "old" Canon printers, the package cups-backend-bjnp is needed. First install it:

sudo apt install cups-backend-bjnp

Then your printer will be avaliable in Ubuntu's list of printers. And you may change the color model to KCMY.

Since the PPA does not yet have packages for Jammy, you can manually install the version for Impish.

Open a terminal and enter the following commands one by one. These commands will download the .deb packages from Launchpad, and install them manually.

mkdir libpng
cd libpng
wget https://launchpad.net/~linuxuprising/+archive/ubuntu/libpng12/+files/libpng12-0_1.2.54-1ubuntu1.1+1~ppa0~impish0_amd64.deb
wget https://launchpad.net/~linuxuprising/+archive/ubuntu/libpng12/+files/libpng12-dev_1.2.54-1ubuntu1.1+1~ppa0~impish0_amd64.deb
wget https://launchpad.net/~linuxuprising/+archive/ubuntu/libpng12/+files/libpng3_1.2.54-1ubuntu1.1+1~ppa0~impish0_amd64.deb
sudo dpkg -i *.deb
sudo apt install -f
