Why bugs and ignore linux_signing_key.pub?

Package Management – Install Kompozer in Ubuntu Budgie 19.04

I am not an experienced user, please take me with you. I tried to install KompoZer from two different sources, but none worked.

First, I downloaded a .deb file from here (https://download.cnet.com/KompoZer-for-Debian-and-Ubuntu/3000-10247_4-75219243.html), but my package installer could not install it. The dpkg command did not work either. When I run sudo dpkg -i /home/jesus/Downloads/kompozer_0.8_b3.dfsg.1-0.1ubuntu2_amd64.debI receive the following:

(Database is being read ... 255283 Files and directories are currently installed.)
Unpacking is being prepared ... / kompozer_0.8_b3.dfsg.1-0.1ubuntu2_amd64.deb ...
Unpacking kompozer (1: 0.8 ~ b3.dfsg.1-0.1ubuntu2) over (1: 0.8 ~ b3.dfsg.1-0.1ubuntu2) ...
dpkg: Dependency problems prevent the configuration of kompozer:
kompozer depends on libpng12-0 (> = 1.2.13-4); However:
Package libpng12-0: amd64 is not installed.

dpkg: Error while processing package kompozer (--install):
Dependency problems - leave unconfigured

There were errors during processing:

I tried to install the libpng12-0 from (https://packages.ubuntu.com/xenial/amd64/libpng12-0/download). However, I have another problem:

(Database is being read ... 255283 Files and directories are currently installed.)
Unpacking is being prepared ... / libpng12-0_1.2.54-1ubuntu1.1_amd64.deb ...
Libpng12-0: amd64 (1.2.54-1ubuntu1.1) is unzipped ...
dpkg: Error while processing the archive /home/jesus/Downloads/libpng12-0_1.2.54-1ubuntu1.1_amd64.deb (--install):

Triggers for libc-bin (2.29-0ubuntu2) are processed ...
There were errors during processing:
/home/jesus/Downloads/libpng12-0_1.2.54-1ubuntu1.1_amd64.deb

Then I tried this PPA (https://launchpad.net/~giuseppe-iuculano/+archive/ubuntu/ppa), but it also fails. When I type "sudo apt-get install kompozer", I get the following:

Read package lists ... Done
Create dependency tree
Status information is read ... Done
kompozer is already the latest version (1: 0.8 ~ b3.dfsg.1-0.1ubuntu2).
You may want to: - apt --fix-broken install & # 39; to resolve these issues.
The following packages have unfulfilled dependencies:
kompozer: Depends on: libpng12-0 (> = 1.2.13-4), but can not be installed
E: Unfulfilled dependencies. Try & # 39; apt --fix-broken install & # 39; without packages (or specify a solution).

I saw some answers to similar problems with installing Kompozer on this site, but they did not work for me.

Any ideas? Many Thanks.

Dual Boot – Help me to install Ubuntu 18.04 (No root file system defined, error):

I'm trying to install Ubuntu next to Windows 10. I have the legacy BIOS and my hard drive partition is MBR. I have downloaded Ubuntu 18.04 and loaded with Rufus on a USB flash drive. I also created 30 GB of free space for Ubuntu. However, if I try to install Ubuntu when I choose the free space, the change function will not be accessible, and when I try to install it displays "No Root File System Defined". Please fix this from the partitioning menu. "Would be great if someone could help me figure that out screenshot_1 screenshot_2

System can not boot on Ubuntu 18.04.2 with full SSD

I got to know the following problem a few weeks ago. I've noticed that my SSD is full, and I wanted to delete some of my useless data to free up memory. For some reason I could not empty the trash after deleting the files. I thought it had to be a kind of bug, so I rebooted my computer. After the restart, the boot process was aborted while loading the Ubuntu logo. I had to reinstall the whole system. Does anyone know what it might cause and how I can prevent such things?

ubuntu – Replace systemd-machine-id-setup with alternative?

We use one Ubuntu 4.18 Template in a virtualization environment. Therefore, we always empty the before you create the template / etc / machine-id File to be recreated on first startup.

The problem is that if multiple Ubuntu 18-based VMs are started at the same time, systemd-machine-id-setup generates the same ID for all, resulting in IP duplicates. I have checked these servers and they all have the same content in the / etc / machine-id File.

IP duplication

When machines are switched on at staggered times, different IPs are assigned, so I assume systemd-machine-id-setup is (possibly) generated based on the current time. This is not acceptable to us because of the problem in the picture above.

Is there a way to let the operating system generate this? / etc / machine-id at boot based on an alternative binary file?

Permissions – Sudo: / etc / sudoers is world writable – Ubuntu Azure

While there are many answers to this problem, the scenario is different here.

I use

I made sudoers file to world writable sudo chmod o + w / etc / sudoers A corresponding solution can be found here.
For that I need Ubuntu user password.

Enter image description here

The authentication mode selected during deployment of the VM was based on SSH. There are other ways to fix it as described here. Neither I could reset the password for Ubuntu, nor the azure cli is accurate.

Let me know how to fix it or if you need more information
