[2.10.2] Open Location fails: volume doesn't implement mount

[marcelpaulo]

Opening an image from a HTTPS location fails with error:

volume doesn't implement mount

Here's a screenshot when I tried to open https://www.howtogeek.com/wp-content/uploads/2016/04/img_571c03f856528.png:

The error is the same for HTTP locations. The flatpak version doesn't have this issue, so it's not a GIMP generic issue.

I'm running GIMP 2.10.2 on Xubuntu 18.04.

This is likely due to the fact that I didn't give gimp network access permission. I did not think it likely that gimp would ever need to be able to access the network in it's job of editing images. I can add the plug to give the snap permission to access the network, though I'm not sure it is a good idea.

I use it frequently, I'd imagine it's common, for getting and editing images from the Web, instead of saving the image locally and then opening it on GIMP. I configured Clipman to open GIMP whenever an image URL is copied to the clipboard, so, editing an image on the Web boils down to right-clicking on the image and then (on Chrome) on Copy image address. It's a lean workflow, as long as GIMP has network access.

I much preferred snap GIMP than flatpak GIMP: it loads much more quickly and snap updates work out of the box (I had to set up a systemd timer to fire flatpak updates daily). But I installed flatpak GIMP because it has network access, so it fits in my workflow.

Actually, I'm just waiting for snap GIMP to get network access, when I'll ditch flatpak GIMP once and for all and install snap GIMP.

Similar issue is still present in 2.10.24 and with all permissions available to be enabled.

The UI doesn't indicate any error code at all though but it just doesn't show any progress

The console is printing out following:
