1) Unless there's something that's been added in 4.5 or 4.6 that you really need and it hasn't already been backported to 4.4 in Ubuntu, then not really. 2) Highly likely yes. Even if 4.6 does fail to boot for whatever reason, you could always boot back into 4.4 then get rid of 4.6. 3) There's a very easy way: ...

I also had the same problem. First, I purge the entire samba, then I changed the software source to the main sever, and finally I installed samba. It is working now. sudo /etc/init.d/smbd status sudo apt-get install libnss-winbind* libpam-winbind* samba* winbind*

If you can't boot into a root shell you're kinda boned. I've seen this happen before when people forget to change the access on the key file. The recommended method is to attempt to use the key before turning off password based authentication. If it's an instance in a cloud, call your provider and have them reset the password (which may not be free or even ...

To easily fix your sources.listfile you can copy the following block and paste it into your terminal after you switched to be root by sudo su (you need to hit return once after pasting to be back as your normal user): cp /etc/apt/sources.list /etc/apt/sources.list.repairbackup cat > /etc/apt/sources.list << EOF # deb cdrom:[Ubuntu 16.04 LTS _Xenial ...

O.k. the list of commands are most likely resolving this, remind that the options posted are getting more aggressive, so begin best with solution attempt #1. 1. doing a soft reinstall of the packages: sudo apt-get install --reinstall gcc-4.9-base libgcc1 2. doing a forced install of broken packages: sudo apt-get -f install 3. removing by dpkg and ...

I spoke too soon. I chose the upgrade option and after reboot it seems to be running 14.10. Problem is that it destroyed everything I had installed. No more web server or any of the apps. I couldn't remember if I had used the server or desktop when originally built so I reverted the snapshot and started over. This time using the server ISO file. I don't even ...

The culprit where some remains, specifically /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.22 from the PPA for Ubuntu Toolchain Uploads (restricted). Removing this PPA with all of it's packages via sudo ppa-purge ppa:ubuntu-toolchain-r/test fixed the issues.

rc mysql-server-5.5 means, that the package is uninstalled (r), but some configuration files remain (c) (in case you want to install it again later). In order to remove them (and make the package disappear from dpkg -l altogether), use sudo apt-get purge mysql-server-5.5.

Upgrading Ubuntu will not affect Windows installation. But upgrading Windows may overwrite grub. It can be easily restored though.


2

If you have a previous installation of Ubuntu you can instruct the Ubuntu installer to use its partition(s). That means that the installer won't need to touch the Windows partitions, so there's only a minuscule chance that the installation accidentally alters Windows despite that fact. You'll need to use manual partitioning during installation though. As ...

I actually had to change some settings before I was able to upgrade. What I had to do was go into system settings>>software and updates>>updates tab. Then I set the parameter for notifications of a new version of ubuntu to "for any release". Then I was able to use the software updater to check for new versions. I am now upgrading to 15.10.

Go here: http://old-releases.ubuntu.com/releases/14.10/ Select the version you want (ubuntu-14.10-desktop-amd64.iso or ubuntu-14.10-desktop-i386.iso etc) and download it. Either burn it to disk or make bootable USB. You can use unetbootin to create a bootable USB. If not installed, do sudo apt-get install unetbootin in terminal to install it. Boot from ...

It's perfectly safe to delete the old versions of the files once the new version has been installed. The only exception would be if you wanted to roll back to an older version of VirtualBox, though that would entail installing it outside of the normal apt framework, so is quite unusual. Also all of the previous extension packs are still available on the ...

You can try to force the installation of the packages by : sudo apt-get dist-upgrade Note: dist-upgrade can be quite dangerous. It will install all pending updates, with their new dependencies. It could delete packages. It could leave you with a very broken system. https://debian-administration.org/article/69/Some_upgrades_show_packages_being_kept_back ...

That error number suggests that you have something in your 'mysql' database (the one it uses for settings) that is incompatible with this version of mysql. The plugin could not be loaded to handle that bit of data and that is preventing mysql from loading. I'm guessing its a maria db thing that is not supported in mysql. One way round this would be to ...

That message comes from the file /etc/issue and/or /etc/issue.net. I would imagine that you either lost these files or they are not readable by root (?!?) or they do not get printed anymore. The files should automatically have been updated. It would be set to the output of lsb_release -d or something of the sort. If that does not work for you, you could ...

I had the same problem as you have. I did EXACTLY what you did and ended in same results: upgrade failed! When you change Ubuntu version you do an upgrade. A (ubuntu) distribution upgrade.

I came across your question just now as I had exactly the same issue. I found the answer in this question solved the issue for me. In my screen I had to ensure "Allow louder than 100%" was checked before the "unamplified" setting was visible.

Failed to fetch Fetching the upgrade failed. There may be a network problem The message may indicate that you need to check your connection or the upgrade servers. They may be down for the moment. But it actually means that is trying to upgrade to 14.10, instead of 15.10 or 16.04 LTS, which is EOL and therefore the packages are missing on the ...

Try: Edit the file /etc/update-manager/release-upgrades . Change the value of "Prompt" from "normal" to "lts". Then try sudo do-release-upgrade -d. See if that works.

Thanks Hi-Angel. The issue here was indeed a package version conflict situation. It turns out that I backported that 3.8.4 sqlite3 package from (then) Debian Testing about 2y ago, and then completely forgot about it. Evidently. I didn't use a PPA, so got only the 64-bit packages. I solved the issue by grabbing an even more recent 3.8 version (3.8.11) from ...

A clean install of Ubuntu 16.04 should have no files in directory /var/log/dist-upgrade. So you could test for the existence of main.log there to determine if the installation was a clean install or an upgrade, eg using bash if [ -f /var/log/dist-upgrade/main.log ] then echo upgrade else echo clean install fi For more info refer to DebuggingUpdateManager ...

did you try apt-get -f install? The Link "http://archive.linux.duke.edu/ubuntu/ wily-security/main" does not exist on my computer either. However "http://archive.linux.duke.edu/ubuntu/dists/wily-security/main" exists. Maybe you have to change the links in /etc/apt/sources.list or inside the directory /etc/apt/sources.list.d.

A purge and reinstall fixed all apt problems: sudo dpkg --purge grub-pc grub2 grub-gfxpayload-lists sudo apt-get -f install # the following gives the prompts: sudo apt-get install grub-pc grub2 grub-gfxpayload-lists I've restated the question better (and without the apt problems) here: grub2: update-grub failed to get canonical path of `none'

The reboot is required because the kernel been updated with fixes to security issues. The fixed kernel can only be loaded on the next boot, hence the reboot is required. If you don't reboot, your machine will not pick up the kernel security fixes until the next reboot.

If you want to upgrade from 12.04 LTS to 16.04 LTS, you can't do that. You can't skip an LTS release like that. You need to update 12.04->14.04 and then 14.04->16.04. It will probably be quicker to just do a reinstall (and setting up your server so it'll be easier next time ;) ).

I got this same problem and "fixed it" by downgrading to the version of apt present in 15.10. In my case, I did the following: sudo add-apt-repository 'deb http://archive.ubuntu.com/ubuntu wily-updates main' sudo apt-get update # and ignore the errors sudo aptitude install apt=1.0.10.2ubuntu2 And choose the less disruptive option.

Select 'For Long Term Support Version' at 'Notify me of a new Ubuntu version'. Now run the sudo apt-get upgrade from terminal and see updates are avail for you.

For better support please upgrade to Ubuntu 16.04+, but we will still attempt to provide support. As for your question, sometimes there is enough blame to go around. For example, 15.10 is an old version, meaning newer extensions may not be programmed to run with it, but instead to function with 16.**. Another reason could be Mozilla's very known ...

The old php5-* packages are coinstallable with the new phpX.Y-* scheme, so the first thing you need to do is to install and enable new packages: Apache 2.4 You need to install new libapache2-mod-phpX.Y packages and then disable the old php5, and enable new versioned module, f.e. for PHP 5.6: sudo apt-get install libapache2-mod-php5.6 sudo phpdismod php5 ...

For me, this command worked: sudo /etc/init.d/network-manager restart I used to need this command for my Chromebook running 15.04 whenever it woke from suspend. It came from some thread.

A quick way to solve this issue is generally to reset your Unity settings. This is easy to do, however keep in mind that it will reset the left bar as well, so the icons you put there will not be remembered.
