I used poweroff -f command to shutdown. After that I used GRUB bootloader. There I used tlinux 5.13. It works properly.

While installing lightworks using gdeb. It prompted for that the package have unmet dependency libssl1.0.0 So i tried installing libssl1.0.0 using the following command in terminal

sudo apt install libssl1.0.0

Following message displayed in terminal

Package libssl1.0.0 is not available, but is referred to by another package.This may mean that the package is missing, has been obsoleted, or is only available from another source.

So i searched for the above package in debian & other repo. I Downloaded 'libssl1.0.0' and tried installing but i can't able to install the package. After that i found a post. In that post it was mentioned that

The package libssl1.0.0 was dropped from Ubuntu after 18.04. Newer releases of Ubuntu use the package libssl1.1. 18.04 has both packages

So i installed 'libssl1.1' Ever after installing also i am encountering unmet dependency problem.

Kindly provide me a link to install 'libss11.0.0'

If any other details needed kindly add it in comment

I installed redshift by using the following command in terminal:

sudo apt-get install redshift redshift-gtk

But while running the program i ended up with errors:

So i installed geoclue with the following command:

sudo apt install geoclue

However even after installing geoclue package, I am still facing the same problem.

I know the beep sound from the CPU is to indicate whether the system is running properly or not. However, I want to be able to enable/disable it. Is there any command to enable/disable beep sound from the CPU?

I have done some research: How do I make my PC speaker beep?.

This link seems to be outdated and not applicable for the latest gnome:

[How to disable beep sound] (https://www.cyberciti.biz/faq/how-to-linux-disable-or-turn-off-beep-sound-for-terminal/)

Recently I installed Oracle Java. It worked fine, But with the recent upgrade with Firefox throws an error.

I checked it here, which says:

Starting with Firefox Version 52 (released in March 2017), Firefox has limited support for plug-ins, and therefore will not run Java. Use the Java Control Panel to find the installed Java version.

I double checked the symbolic link also. It is configured properly

$ java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)

How can I run java applets in firefox?

I installed inkscape by using the following command:

sudo snap install inkscape

It is installed correctly, however it is not shown in the application menu.

$ snap list

How can I run inkscape ?

I believe my computer hardware is compatible with this printer, but I'm using Ubuntu gnome 14.04 and I'm unsure whether this is compatible.

Is there a FULL PDF manual on the JUJU that can be printed as oppose to reading on the internet? I prefer a hard copy.

I am having Huawei ec 150 Data card. It works well with the default network programs in Ubuntu. My network provider offers 3g speed upto 1gb for two days There after the speed will drops as per the plan. The problem is that the default program in ubuntu works for 3g speed. when i cross the 1gb data limit i cant able to access the network not signal is being detected. So i have to install driver software for the device. I tried so many ways and installed finally. However the software doesn't detect the network. So kindly provide me the details how should i configure my device.

I'd like to add folders to the nautilus "Places" menu with custom vector icons. There are a few solutions out there but they all address Ubuntu 13.10 and aren't easily ported to 14.04. Ideally I want to be able to:

1. Delete "Recent"(under Places)
2. Set custom icons for the folders

Please don't suggest adding a Bookmark.

Is it possible to use Ubuntu Desktop as a Server? Can I host a website on it? What are the additional packages i need to install to make my system both as a desktop and a server

I'm Using Huawei ec 150 dongle. I need to install driver software It is quiet a big task for begineers in linux. So i took this matter over here.

Most softwares support 32 bit architecture. Some high end software need 64 bit architecture. Can we have both architecture on a single distro ?

I have Ubuntu 14.04. I recently downloaded Viber. The Viber .deb file has 64-bit architecture. I want to install it on my computer, but my computer only supports 32-bit.
