I've started seeing a livepatch warning in my system tray.
Clicking it takes me the the livepatch client where I see this error message:
Despite the URL, there isn't a #CommonIssues section on the page: https://wiki.ubuntu.com/Kernel/Livepatch#CommonIssues
Any ideas how I can fix this?
Ubuntu 18.04.2 LTS
4.15.0-34-generic
I know updated snaps can be reverted back to a previously installed version but is it possible to install an older version of a snap in the first place?
For example, if the version of AmazingApp in the snap store is v1.3, is there a way to install v1.2?
Is there an archive?
On Ubuntu 16.04 I have Network Manager configured to automatically use an OpenVPN connection at system start-up. This works well.
However, when the machine resumes after being suspended, although the VPN reconnects, I am unable to browse (or ping) websites because host names cannot be resolved. For some reason DNS look-ups are failing.
ping: unknown host www.google.com
This only started happening a couple of weeks ago, I'm not sure what has changed.
