I want to upgrade ubuntu server 14.04 LTS to 18.04 LTS without upgrading 16.04 LTS. can you please help me for the same.
No. You can not upgrade.
Ubuntu does have LTS→LTS upgrades, allowing you to skip intermediate non-LTS releases...
But you can't skip intermediate LTS releases. You have to go via 16.04.
Unless you want to do a fresh install of 18.04 on release.
I should also note that the LTS upgrade pathways are usually only available sometime after the main release. So don't expect to be able to upgrade from 16.04 on the day of 18.04's release.

I deployed my Qt Gui application with CQtDeployer on Ubuntu 18.04.
But, I can't run it on Ubuntu 16.04 / Ubuntu 14.04.
It has an error on version.
How can I fix it?
Just build and deploy your application on ubuntu 14.04
Your distribution not run because you build and deploy application on OS that has new version of (libc/libz) library.
So, If you want to create distribution that will be works correctly on all versions of your OS then you need to build and deploy application must early OS version.
Example
Application that was built on ubuntu 16.04 will be works great on ubuntu 18.04 , 20.04 and may be 22.04
But not 14.04 because minimum required libc level is some as on ubuntu 16.04.
How to get cqdeployer on ubuntu 14.04
Install from snap store:
sudo snap install cqtdeployer
sudo snap connect cqtdeployer:process-control
sudo snap connect cqtdeployer:removable-media
sudo snap connect cqtdeployer:system-backup
And NOTE
The ubuntu 14.04 too old. So i recommend to drop support of ubuntu 14.04.
User Ubuntu 16.04 as main build machine.
I'm getting the following error while installing Openstack on Ubuntu 16.04.7. Can someone please help.openstack-error
You are installing a version of OpenStack that is no longer supported on Ubuntu 16.04. You either need to upgrade to 20.04 or 18.04.
An alternative would be to try to install an older version of OpenStack that supports Ubuntu 16.04 by changing the branch you use for Devstack.
git checkout stable/rocky
I wanted to start learning docker, nut the docker docs donot mention the new ltd release of ubuntu 20.04 lts.
i tried installing mongo db on the new ubuntu 20.04 lts, it didnt work, their docs donot mention support for 20.04, so i was skeptical about docker too.
Can anyone verify?
It works fine on my ubuntu 20.04. I upgraded it from 19.10, but still. you can install docker from bionic repo.
I have recently installed Linux Mint on a new machine and I am trying to download virtual box.
The problem is it won't download because of this error:
Error: Dependency is not satisfiable: libc6 (>=2.27)
When I run:
sudo apt-get install libc6
It tells me
libc6 is already the newest version (2.23-0ubuntu10).
When I update the cache of my software sources I get the message that it could not download all repository indexes so I assume it might be related to that but I have no idea how to fix it.
Sometimes it happens when you try to run the wrong version (build) of the application in your system.
As an example, the current Virtualbox version is 6.1.22. And I download it for the Ubuntu 19.10 / 20.04 / 20.10 / 21.04 host because there is no separate download link available for Linux Mint distribution. But my Linux Mint distribution is 19.3 cinnamon and Mint 19.3 is based on Ubuntu 18.04 LTS. So, the Virtualbox version which is built for Ubuntu 20.04, 20.10, 21.04 is not going to work for the distribution which is using Ubuntu 18.04. This is the reason for getting ( Error: Dependency is not satisfiable: libc6 (>=2.29) ) error.
When I downloaded the Virtualbox which is particularly built for Ubuntu 18.04 everything worked fine :)
For more clarity watch this video https://www.youtube.com/watch?v=1K2zx32tBwA
OR, just download the VirtualBox from the Software Center. that will work fine too.
I couldn't solve the issue but I managed to download virtual box through the software manager.
After installing libimobiledevice in ubuntu 14.04, when I run command 'ideviceinfo' it is generating error
'Could not connect to lockdownd, error "code -5"'
I have other dependencies - build-essential
libudev-dev,
libimobiledevice6,
libimobiledevice-utils,
libusb-1.0-0-dev,
libimobiledevice-dev,
libzip-dev
Correctly installed with no error.
Can I get some advices about the error ?
You didn't mention how you acquired libimobiledevice - did you install it via apt-get or did you compile it from source?
Ubuntu 14.04 ships with a very old version of libimobiledevice, and there have been changes made to libimobiledevice to provide compatibility with newer versions of iOS which are probably not in Ubuntu 14.04.
We host a PPA which provides up-to-date builds of libimobiledevice; currently only for Ubuntu 16.04 though. You can find it at https://launchpad.net/~quamotion/+archive/ubuntu/ppa/+packages .
Let me know if you need help configuring the PPA and installing the latest libimobiledevice.
