CKAN Version:

v1.22.3

Operating System:

Debian Linux

The issue you are experiencing:

If I press the left Meta key on my keyboard (a.k.a. the Windows key, a.k.a. Super_L), then ckan instantly crashes. The same happens with Menu, but not with the right Meta key (a.k.a. Super_R).

CKAN error codes (if applicable):

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

This is a Mono issue - it's not CKAN-specific.

See:

Bah. Fair enough.

It looks like WinForms is being replaced with Xamarin Forms, which is also cross-platform --- any plans to rewrite CKAN to use that?

@GinjaNinja32
Copy link

Following the chain of bug reports leads to a workaround which resolves this on my system

$ mono --verify-all <the-mono-program>

In CKAN's case, try mono --verify-all $(which ckan) - you may need to change the path if your CKAN executable isn't the ckan on your PATH.

Yes, that works fine. I've no idea what the flag does, but is there any way to make it the default for Linux?

@GinjaNinja32
Copy link

How do you launch CKAN?

If from terminal or dmenu-like, create a ~/bin/ckan which runs exec mono --verify-all <ckan binary>.
If from a desktop shortcut, find the desktop file it's launching and edit it to run mono --verify-all <ckan binary>.

Hey there! I'm a fun-loving automated bot who's responsible for making sure old support tickets get closed out. As we haven't seen any activity on this ticket for a while, we're hoping the problem has been resolved and I'm closing out the ticket automaically. If I'm doing this in error, please add a comment to this ticket to let us know, and we'll re-open it!
