While performing a backport of apparmor 3 to kernel 3.4, I received the following error:
security/apparmor/lsm.c:1146:2: warning: initialization from incompatible pointer type
error, forbidden warning: lsm.c:1146
There was no more information. gcc didn't even print the erroneous line. The line in question was:
| #!/bin/bash | |
| set -e | |
| # Fetches and prepares a certain tag from system server | |
| # First argument: Channel, like '16.04/arm64/android9/stable' | |
| # Second argument: Device, like 'yggdrasil' | |
| # Third argument: Destination directory | |
| # Fourth argument: Image tag, like 'OTA-16' | |
| # The files created in the destination directory can be pushed to /cache/recovery/ on an Ubuntu Touch device. |

The following is a short discussion on GPS "fixing" or "locking" and the different states that a GPS device may be in when trying to get its first fix. I wrote it for the UBports documentation but it just didn't seem to fit anywhere in the article I was writing. Maybe I'll use it later.
Most GPS hardware in mobile devices does not directly state its expected TTFF or its progress toward acheiving its first fix. To make matters worse, Ubuntu Touch does not currently use a Wi-Fi positioning system or cell-site multilateration. For this reason, it can seem that Ubuntu Touch takes a very long time to receive location data.
If GPS hardware is not used for a while or the device's battery dies, it may need to aquire a "Cold" fix. This means that the hardware does not know the position or velocity of any positioning satellites (the `almanac <https://en.wikipedia.org/wiki/GPS_signals
Sometimes you want to test how an operating system will behave if you act like you're using a different computer model than you really are. For those cases, libvirtd with KVM comes in handy. We can change the model of our computer (the one returned by wmic csproduct get name, specifically) very easily. This can be used with machines created in virt-manager, but the application itself does not provide this configuration for us.
First, open up your configuration with the following command:
virsh edit [VM name]
Now we only need to add a few lines of configuration to the file. Inside the <os> tag, add the following:
