I typically upgrade my machines with: sudo apt-get update && time sudo apt-get dist-upgrade Below is an excerpt from man apt-get. Using upgrade keeps to the rule: under no circumstances are currently installed packages removed, or packages not already installed retrieved and installed. If that's important to you, use apt-get upgrade. If you want ...

Your /boot partition is filled with old kernels. It does that sometimes, not sure why it is never fixed. You can easily remove the old kernels if you know which packages they came in. First check uname -a to check your current version. Then run the following command: dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed ...

Ubuntu only supports upgrading from one version to the next version, or from one LTS version to the next LTS version. So you need to upgrade from 10.04 to 10.10, and only then to 11.04. There are technical reasons for this restriction. When a new version of an existing package is installed it sometimes has to perform conversions, e.g., it may have to import ...

Here is my advice as a tutorial-like answer, based on my experience upgrading. This procedure was tested by me, and it worked as it should. Hopefully this will help others to upgrade without problems. This is not an official guide. Friendly advice There is no reason to rush. There is no reason to upgrade from day one. The new Ubuntu version is not going ...

You will find a clean install a lot less hassle than any other unusual, obscure, unsupported method. Your suggest of partitioning the config files, home directories, etc is probably the best idea, and it is possible to install the same packages on a clean install as on another install. On the other hand, what you requested is possible, there is a little ...

The beta uses the repositories as they are updated -- it is not a fixed snapshot of Ubuntu as it was when the beta was released. If there are no more updates to be installed, then congratulations! You are running the final Ubuntu release. There is nothing else you need to do. Here, have a totally simplified, consumer-side view of a release I hacked ...

Press Alt + F2 and type update-manager -d. On the top of the window you will see an info of the new Ubuntu+1 "release". However, upgrading to a development release is not recommended, as it is a unstable release. See this question for tips when you have problems: There's an issue with an Alpha/Beta Release of Ubuntu, what should I do?

Because Ubuntu 12.04 is a Long Term Support release (meaning that it is supported with bug fixes and security updates for 5 years) you won’t find a pop-up telling you that a new version is available. If you want to upgrade,you can follow these instructions Open Update Manager from either the Power Menu or the Dash. Click the ‘Settings’ button in the ...

apt-get upgrade is restricted to the case where packages are to be replaced by newer versions, but no package needs to be added or removed. A new version of Firefox, for instance, should be installable with apt-get upgrade. However apt-get upgrade will refuse to work when there are additions or removals required by the updated versions. For example, when ...

To update from an older version (very old in this case) than the previous version to the current version is highly not recommended. You are better off downloading the new release, doing a backup and then installing the new release. If you are using Ubuntu 10.04 and REALLY REALLY want to update from that version up to the latest version then keep reading, ...

Githlar's answer removes the warning, without responding to what the warning is telling you. It's actually saying that loading from ~/.fonts.conf will be removed in the future. Hence, Githlar's solution will ignore what will break in the future. The correct thing to do is to move ~/.fonts.conf to ~/.config/fontconfig/fonts.conf . The easiest way to move this ...

I think I've sorted it thanks to a post I found here: Root filesystem check fails after power failure during installation. Run from maintenance shell one line at a time: mount -o remount,rw / dpkg --configure -a mount -o remount,ro / sync reboot Worked for me but only got the first 2 lines and couldn't do the rest as drive was busy. Rebooted and it seems ...

You'll first need to make sure update-manager-core is present (it may already be installed): sudo apt-get install update-manager-core Next, run: sudo do-release-upgrade You may need to check /etc/update-manager/release-upgrades and change the line: Prompt=lts to: Prompt=normal for the release to show up.

The truly command line way is (e.g. if you don't have a gui): sudo do-release-upgrade -d where -d means update to a development version (like 11.04 - natty)

Check that mysql-server-5.1 package was uninstalled, seems it might persist after upgrade. I had the same error and had to purge MySQL server 5.1 and 5.5 then re-install. First make a backup of your /var/lib/mysql/ directory just to be safe. sudo cp -R /var/lib/mysql/ ~/mysql Next purge MySQL (this will remove php5-mysql and phpmyadmin as well as a ...

@Marco-Ceppi 's solution is already integrated into do-release-upgrade. When you run do-release-upgrade it starts a screen session automatically. If your ssh session gets disconnected, you can resume the installation. All you have to do is open a new ssh session, and run do-release-upgrade again. It will reconnect to your previous installation. A second ...

Freeing Up Space on the Root File System To free up space on the root file system you can try to execute apt-get clean. If that doesn't work you can go to /var/cache/apt/archives and manually remove a few files from the cache to get some space back, e.g.: sudo rm linux-headers-* It won't hurt to remove all of the .deb files here if you need to--that is ...

You do not have the Heartbleed vulnerability on your server, OpenSSL has been patched to fix this issue (without upgrading it). You have left out several important lines in the OpenSSL version output, that's how you know it's been patched, not with the version number: openssl version -a ✭ ...

The simplest set of instructions I always used for kernel upgrade / downgrade are by ubuntuforums.org user by the name of lykwydchykyn (url modified by me for this post): Go here: http://kernel.ubuntu.com/~kernel-ppa/mainline/ Download 3 (maybe 4) debs to a folder somewhere: linux-headers-VERSION-NUMBER_all.deb linux-headers-VERSION-NUMBER_amd64.deb ...

What I would recommend doing is launching a screen session on the server and running the upgrade in screen - that way if your SSH session drops (for whatever reason) the upgrade process will not halt. Screen is a program that allows for persistent terminal(s) on a machine. So you can start a screen session and so long as the machine is on that screen ...

Typically, upgrades are just fine in Ubuntu. It's not like Windows where you have a huge registry to carry over from your last system. As long as you haven't had to follow many tutorials or done any workarounds to fix problems in a unique way (i.e. using a special application to enable your wireless card or made some major changes to your kernel for whatever ...

You cannot skip versions between upgrades. The version between Jaunty and Lucid is Karmic. I suggest you do backup important data and do a complete reinstall as many things has changed, including the boot loader. If you do not like a fresh install, you can upgrade using an Alternate CD. Preparations: Backup the system (if possible a disk image) Backup ...

You need to increase the maximum size of a chunk of shared memory Linux kernel allows to allocate at once (known as SHMMAX parameter) You need to edit /etc/sysctl.conf and add the following line: kernel.shmmax = 41943040 (where 41943040 is the size of memory in bytes, i.e. 40 megabytes. On production system you probably want to set this value way higher ...
