Faced a similar one with Fedora 28. Disabling the host checker will fix this issue.
How? Can you do that in the client (only)?
No, it has to disabled on the user realm.
The kernel related issue is fixed, but another issue has been identified because of which the client still remains incompatible with Ubuntu 18.10
This issue will be fixed?.
Do you have an estimated date of resolution?.
The second issue has been raised. The team is working on it. Will update with the dates once it is finalized
