install gphoto2 without libgphoto

I've been trying to install gphoto 2-2.5.20 and libgphoto2-2.5.22 but whenever i install gphoto it uses the older libgphoto2-2.5.12 which dosn't work with my camera(Olympus E-M1 Mark II) . Is there any good tutorial out there how to install everything properly ? cant find anything

Thanks for answers

According to NEWS file of libgphoto2 the support for your camera was added in version 2.5.19.

For Ubuntu this means that you need to have Ubuntu 18.10 (cosmic) or future 19.04 (disco). Both versions are non LTS.

So on Ubuntu LTS you need to compile gphoto2 and libgphoto2 by yourself.
Below is the method for Ubuntu 18.04 LTS:

1. Enable Source Code repositories from Sofware & Updates (software-properties-gtk)

2. Install build tools and build dependencies for gphoto packages:

   sudo apt-get install build-essential git devscripts
   sudo apt-get build-dep libgphoto2-dev gphoto2

3. Clone source code from Debian (we will get version 2.5.20-3 for both gphoto2 and libphoto2 for compatibility):

   cd ~/Downloads
   git clone -b debian/2.5.20-3
   cd libgphoto2
   rm debian/source/format # disable 3.0 (quilt) format
   dpkg-buildpackage -uc -us
   sudo apt-get install ../libgphoto2*.deb
   cd ~/Downloads
   git clone -b debian/2.5.20-3
   cd gphoto2
   rm debian/source/format # disable 3.0 (quilt) format
   dpkg-buildpackage -uc -us
   sudo apt-get install ../gphoto2*.deb

4. Check that gphoto packages were installed (compare with output below):

   $ dpkg -l | grep gphoto
   ii gphoto2 2.5.20-3 amd64 digital camera command-line client
   ii libgphoto2-6:amd64 2.5.20-3 amd64 gphoto2 digital camera library
   ii libgphoto2-dev:amd64 2.5.20-3 amd64 gphoto2 digital camera library (development files)
   ii libgphoto2-dev-doc 2.5.20-3 all gphoto2 digital camera library (development documentation)
   ii libgphoto2-l10n 2.5.20-3 all gphoto2 digital camera library - localized messages
   ii libgphoto2-port12:amd64 2.5.20-3 amd64 gphoto2 digital camera port library
   $ gphoto2 --version
   gphoto2 2.5.20

   This version of gphoto2 is using the following software versions and options:
   gphoto2 2.5.20 gcc, popt(m), exif, cdk, aa, jpeg, readline
   libgphoto2 2.5.20 all camlibs, gcc, ltdl, EXIF
   libgphoto2_port 0.12.0 iolibs: disk ptpip serial usb1 usbdiskdirect usbscsi, gcc, ltdl, USB, serial without locking

I do not have any DSLR for test, but I hope this method will work.

Also note that many GUI applications use gphoto2 library as back-end to communicate the camera. You can try digiKam, DarkTable, Entangle. All they have packages in official Ubuntu repositories.
