Problem installing Photoflow in Ubuntu

Hi
I’m very much a newbie with Ubuntu - I installed it a few weeks ago because I wanted to use Darktable. Additionally, I tried to install Photoflow but got the following error message in Terminal. I’m probably doing something really stupid! Any ideas?

Which version of Ubuntu have you installed? Have you added this PPA?

That was quick!
I have installed 16.10 and used these instructions from your website;
sudo add-apt-repository ppa:dhor/myway
sudo apt-get update
sudo apt-get install photoflow

Thanks

Then I suggest that we involve @Dariusz_Duma, the maintainer of the PPA, in this discussion…

Since there’s libvips42 in main repository, this is quite strange.

Ok, so let’s check why libvips42 can’t be installed. Show output of:

sudo apt-get install libvips42

Ok, we’re making progress :slight_smile: But libvips42 in 16.10 repository doesn’t need libcfitsio2, so…

Show me:

apt-cache policy photoflow
apt-cache policy libvips42
