Ubuntu 16.04 cannot be installed under QEMU / KVM: ldlinux.c32 could not be loaded

I am trying to install 32-bit Ubuntu 16.04, which I download here. I always get the same error. The screenshot of ldlinux.c32 could not be loaded here. However, I tried installing the 64-bit version of Ubuntu 18.04 LTS and was able to install it successfully. Help? Thank you very much.

NB: Ubuntu 18.04 LTS (Bionic Beaver) runs on the host

Dell XPS 13 touchpad problem after updating the kernel in 16.04 lts and 18.04 lts

askubuntu doesn't just let me highly value an answer from these other guys that worked for me. Long story short, I updated the kernel in my April 16, which has been running on my XPS 13 for several years. It blocked my trackpad mouse, but the USB mouse worked fine. Upgrading to 4/18 in the hope that this would fix my problems. it has not. came here to find answers. A number of the solutions offered did not work. Finally these people did it.

Thanks a lot!

The answers described in this post do not solve the problem in Ubuntu 18.04.x ​​because it is a kernel 4.15.0-72 error. (There may be other old kernels with the same problem.)

Solution: use a different kernel (more preferred)

1.You can use ukuu to upgrade / downgrade the kernel

sudo apt-add-repository -y ppa: teejee2008 / ppa
sudo apt install ukuu
2. You can use hwe from PPA (recommended):

sudo add-apt-repository ppa: canonical-hwe-team / ppa
sudo apt install –install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

gnome – Some of the keys r, q did not work, only works with Shift Ubuntu 16.04

The random r key on the keyboard does not work on the Gnome terminal. It only works with Superkey + r.

Googled it and checked the keyboard layout for r keys dconf Editor. No link has been assigned. verified event tracing with xev Command, no event was generated for the r key.

https://unix.stackexchange.com/questions/231307/key-for-the-letter-o-stopped-working-only-with-shift-linux

Tried from the link above "killall gnome-settings-daemon" makes the r keys work. I try to understand the process behind it, but I cannot understand it. Please someone help me with this.

How does the r key not work before the Gnome Settings daemon has ended?

I try to install Mono with mono-complete, but that happens:

sudo apt install mono-complete

Some packages could not be installed. This can mean that you have
requested an impossible situation or if you are using the unstable

How can I fix this?

16.04 – The laptop webcam can not be used under Ubuntu 18.04 under VirtualBox VM with Windows 10 as the host operating system

I am using the latest stable version of VirtualBox (6.0.14) and have installed the appropriate extension package so that I can click on the VM menu Devices -> Webcams -> "MyWebcam" while the VM is running. This creates / dev / video0 and / dev / video1, but when I try to use them with either cheese or the VLC GUI, an error occurs.

I have followed the solution fairly closely in this case. How can I use my webcam with Ubuntu running in VirtualBox? but I think there is something second to the answer, but I can not understand the steps he has made (on which computer should I take these steps, on the host operating system or on the guest operating system?)

Any help would be appreciated.

16.04 – Systemd-tmpfiles do not work due to insecure symlinks, not sure what that means

I've noticed that sshd has not started lately and I've found that it has something to do with / var / run / sshd. Well, I can create this directory, but since it's a tmp directory, it will not work on the next boot. I see that the problem is the following errors with systemd-tmpfiles. I see other posts on this topic, but their problem was a wrong user / group of root or run, which is not my problem as both are shown as root.root. What should I check?
