Master site for `graphics/camera` returns 404 (http://download.gna.org/gsimageapps/), also unable to open to gna.org.
CC'ing the last contributor to the port, just in case.
I think it is useful app, I might be able to adopt it as a port maintainer.
# cd /usr/ports/graphics/camera
# make fetch
The camera port currently does not have a maintainer. As a result, it is
more likely to have unresolved issues, not be up-to-date, or even be removed in
the future. To volunteer to maintain this port, please create an issue at:

Thank you for the report Petr.
If you would like to maintain the port, please include a patch as an attachment updating MAINTAINER and fixing MASTER_SITES after identifying an authoritative and reliable source for the distribution file
I suspect that the site has gone offline for good (especially since maintainer was dropped from the port for some time), I'll see if there is a fork of it available somewhere. If not, is maintaining the code in a new Github repository an acceptable solution?
(In reply to Petr Penzin from comment #2)
That is an acceptable solution (for now). If you could, please note explicitly in the repository README that it is a fork/holding area for the code since the original upstream was 404, and use the repository URL in the ports pkg-descr WWW: line so that users are explicitly aware of its status.
Thank you for taking the time to resolving this Petr

I've added the code here: https://github.com/gsimageapps/Camera
There are a few other ports that used to pull from the same site, I'll see if I can make sense of those and move them to the same Github orgn unless there is a better fork somewhere already. If you end up creating bugs for moving that code, feel free to assign them to me.
(In reply to Petr Penzin from comment #4)
Thanks for that. Feel free to attach a patch updating this port to use these sources, and I'd also be inclined to recommend including changes to any other ports that use the same (now 404) MASTER_SITES in the change, so they can all be updated at the same time.
A cursory search across the ports tree finds the following matches:

Oh, that is quite a bit! I thought that only hosting for the image apps went down. Looks like it is the fallout from this: https://en.wikipedia.org/wiki/Gna!
I'll try to see if they migrated elsewhere first, Camera certainly did not -- at least I could not locate any more mirrors.
(In reply to Petr Penzin from comment #6)
That'd be great Petr. In the mean time I think its probably worth converting this into a broader issue to cover all the other ports, and people update those ports individually, but referencing this single issue in commit logs
