I am from Opera and we noticed that Opera stops working today after updating to use core18 to snap Opera.
$ opera
You need to connect this snap to the gnome platform snap.
You can do this with those commands:
snap install gnome-3-28-1804
snap connect opera:gnome-3-28-1804 gnome-3-28-1804
On my machine, I can solve the issue by running the following commands:
sudo snap refresh core18 --candidate
sudo snap revert opera
sudo snap refresh opera
Should we request an auto-connection for gnome-3-28-1804?
We already reverted Opera on the store. The snap.yaml with this issue is attached below.

With this change, we no longer see the complain about connecting gnome-3-28-1804. However, some machines have an error about GdkPixbuf instead:

This likely means that your installation is broken.
Try running the command
gdk-pixbuf-query-loaders > /home/radek/snap/opera-developer/common/.cache/gdk-pixbuf-loaders.cache
to make things work again for the time being.

Does anyone know about this? Any idea will be appreciated.
@xshi on the machines complaining about the missing gdk-pixbuf-loaders.cache, please rm -rf ~/snap/opera (or ~/snap/opera-developer, whichever is broken), and try relaunch the snap. It sounds like the cache may have gotten corrupted in one of your install cycles during testing.
@marcustomlinson Thanks for your reply. I removed the opera folder (~/snap/opera-developer in my case) but it doesn’t help. I noticed that the folder ~/snap/opera-developer/common is empty on the machines that Opera does work, but it is not on a failing machine (I can only check one currently). I am not sure if this is relevant.
You mean you remove ~/snap/opera-developer then run the snap and on some machines ~/snap/opera-developer/common is repopulated, and on some it isn’t?
Could it be that you think nothing’s there but really there is a hidden .cache folder present?
You are right. ~/snap/opera-developer/common on all machines has content. Sorry I had that wrong conclusion (not all ll alias includes -a). But removing ~/snap/opera-developer folder or reinstall the snap package doesn’t resolve the issue.
Looking through logs, I notice these error in the first run after I reinstall the snap package:
cp: cannot stat '/snap/opera-developer/78/gnome-platform/usr/share/mime': No such file or directory
Directory '/home/opera/snap/opera-developer/78/.local/share/mime/packages' does not exist!

I first ran these four commands and installed build 75, which is using the legacy desktop support. I got the issue about connection to gnome-3-28-1804 (my initial issue).
Then I ran the four commands again and this time I install the edge one (build 78). Unfortunately, I still get the issue about gdk-pixbuf-loaders.cache.
/snap/gnome-3-28-1804/current/usr/share/mime does exits.
The machine has kernel 5.0.0-25-generic, which is older than the working machine. I will try upgrading it tomorrow.
Sorry I can’t follow up the issue for a long time. I am wondering what do you meant by “permissions issue”? It’s about the user permission to some path or it’s related to snap’s confinement?
I installed a new 18.04 VM and I can reproduce this issue there.
The folder /snap/gnome-3-28-1804/current/usr/share/mime on VM contains much less data comparing to my working machine.
However, after updating the system through Software Updater and restart, Opera is finally running if I update the system through Software Updater, and manually connect gnome-3-28-1804 interface:
