"Flawless" is subjective since not even Windows on the SP3 is without issues. With 15.04, there is only one issue that I am concerned with, battery/suspend. I basically never shut down. I have a 1 hour commute to work by motorcycle and it never has an issue. Uses about 10%/hr when just sitting idle. I found you need to disable suspend completely in ...

14.10 Utopic has been released (in October last year) and is stable, but is newer than 14.04 LTS Trusty (which could be 'more stable') - 15.04 Vivid is in development and will be released in April. See more here As for GNOME, Ubuntu sort of misses out on newer versions due to the timing of GNOME's release and Ubuntu's. So if you want to install a newer ...

I did some digging around in the code for do-release-upgrade. It appears that it downloads a file from http://changelogs.ubuntu.com/ to check for new releases. It downloads different files from there depending on the command line options provided. The file that would suit my needs is http://changelogs.ubuntu.com/meta-release I don't see any options that ...

It says using the flag -f. That's an option. But you can also use this: sudo apt-get update && sudo apt-get dist-upgrade

Try this fix: From a terminal: sudo apt-get update sudo apt-get install unity dconf reset -f /org/compiz/ This will reinstall unity and reset the config. If that doesn't work then: sudo apt-get update sudo apt-get install ubuntu-desktop rm --recursive /home/user/.config/dconf/user but be aware that this solution will install ...

Try pressing Ctrl+Alt+F1. That should allow you to enter tty1. If that doesn't work, try Ctrl+Alt+F2, Ctrl+Alt+F3, etc. etc. It will say something like: Ubuntu 14.10 ComputerName tty1 ComputerName Login: Type your username here and hit enter, and then your password. You should be able to access tty and go from there.

With two installs you have to normally do two updates. Whichever system's grub is in MBR must be booted and sudo update-grub run to find newer kernel in second install. But since you have two drives, put main working install's grub into the MBR of sdb. And keep test install's grub in MBR of sda. When you install grub defaults to sda. Better to use Something ...

Installation details for specific package versions on Ubuntu can be found here. As for the breaking Wordpress 4 I can't find any know bugs right away. However if you are really nervous then do the upgrade in a test environment first.

You can upgrade lxc-docker specifically: sudo apt-get install lxc-docker That should override whatever holds back the upgrade (barring manually held packages, which we excluded in this case).

I had to reinstall the NetworkManager package and reboot. Everything was fine then. sudo apt-get --reinstall install network-manager

Here is the caveat: no network upgrade, strictly from cdrom. This is the alternate way to upgrade Ubuntu 12.04.3 to 12.04.4 (but can apply to other versions as well): Download and mount cdrom (/media/cdrom; or /cdrom) ubuntu-12.04.4-alternate-amd64.iso file downloaded from Ubuntu website (http://cdimage.ubuntu.com/ubuntu-core/releases/12.04/release/) ...

It sounds like you have the python-numpy package installed in Ubuntu, and you also installed the package using pip. You probably want to remove the python-numpy package. See apt-get install vs pip install for more information.

In my experience falling back to gnome after installing Trusty, these answers are not fully adequate. I found the Metacity option preferable to the compiz for two reasons right out of the box. Metacity comes set up with four workspaces, while this has to be configured in compiz and I found the configuration not straightforward as apparently there are two ...

I've done this task before starting with a Pentium 4 computer that had 512MB RAM and no graphics card. I don't believe that a Pentium 4 computer can run Ubuntu 14.04 satisfactorily, so I downloaded Xubuntu 14.04 32-bit. I also added another 512MB of RAM. I could have used two 1GB RAM sticks instead, but I added only one 512MB RAM stick because it was what I ...

Go to System Settings > Software Updates and uncheck the CD-ROM checkbox at the bottom of the leftmost tab. This will remove your installation media from the repository list. You could also do this by manually editing (with root privileges!) the file /etc/apt/sources.list and replacing every cdrom at the beginning of a line with #cdrom (the # marks the ...

As per this answer the automatic updates doesn't even know that the cuda 6.5 is installed nor any of its dependencies that were installed with it, so you are safe tu run an upgrade. That being said, nothing is 100% certain, therefore take a full system back-up of your PC (you're definitely user type 4) and then proceed with the upgrade. If the upgrade ...

This will work better than these solutions: sudo apt-key list You will see this on this list: pub 1024D/7FAC5991 2007-03-08 uid Google, Inc.

Emacs 24.4 is still relatively new. Ubuntu is considered a stable distro, and for that reason software sometimes lags behind. If Emacs 24.4 isn't packaged, you'll need to build it yourself. You can find comprehensive instructions on how to install GNU Emacs 24.4 on Ubuntu in this guide: ...

Converted from a comment as per David Foerster's request and multiple upvotes. What I'm gathering from your question is that you need to put a new hard drive in your computer and want to simply install Ubuntu. As far as I know, you should be able to install Ubuntu just fine, so long as you get the right version for your CPU. You can't install 64 bit ...

You might have a corrupted file, so try removing and reinstalling the libf2c2 and libf2c2-dev packages: sudo apt-get purge libf2c2-dev sudo apt-get purge libf2c2 sudo apt-get install libf2c2 sudo apt-get install libf2c2-dev The question you refer to has another problem, their file is a python script, so of course it is not an ELF file.

This answer is more for completeness at this point; use the OEM driver available from: http://www.geforce.com/drivers You will need to run the driver install script from a root terminal, and kill all the X related processes before running it. You may also need to chmod +x the script. It is also note worthy, that the OEM driver recompiles the kernel. If ...

Try creating a file in that folder and executing the uninstall command then: sudo mkdir -p /usr/java sudo touch /usr/java/aa sudo touch /usr/sbin/alternatives sudo apt-get remove jdk1.8.0-40 EDIT: Try this: echo "" | sudo tee /var/lib/dpkg/info/jdk1.8.0-40.postrm

QT Creator needs libglew-dev which is not available for 14.04.2 yet. What you can do: Downgrade the kernel and use the version for trusty version of kernel and relative drivers. Wait for the upgrade

The data will be never lost during an update: your data is stored in /home directory, and the upgrade affects the other parts of the system. What might be lost are your app settings and your desktop preferences (it didn't happened never when I made release upgrades, through.). If you are paranoid, backup your important data to an external HDD, disconnect ...

Something is apparently running already on ports you're trying to bind to. What is it? You'll have to find out yourself, I'm afraid. What may help you with that is anyway netstat command. Try netstat -nap | grep 8080 (or 8081) to find out which process is using this port.

I'm going ro answer my own question. This appears to be a recurring bug which has been reported on Launchpad back in 2013. Every version of ubuntu since is affected by this but not everyone sees the error. On the moment I write this (march 2015) there's no permanent solution, however there are workarounds to solve the problem. For Ubuntu 14.10 the problem ...

I had the exact same problem, and this worked for me: I installed the 14.04 (trusty) versions of those same packages first: sudo apt-get install --install-recommends linux-generic-lts-trusty xserver-xorg-lts-trusty libgl1-mesa-glx-lts-trusty libegl1-mesa-drivers-lts-trusty Once I installed those, I was able to run the command to upgrade the enablement ...

Problems like this happen a lot during an upgrade. I recommend that you simply install 14.04 over your existing setup. You'll want to backup your /home directory but most installs will save that. The reason this happens IMHO is when the config files are updating they don't always update correctly. I've actually seen Linuxes where this is a listed "upgrade ...

g++ does support c++11, but it is experimental, hence you have to enable it with the option -std=gnu++11. You don't need to upgrade g++, you can't, because you are already running the latest version. So you will compile using a command like g++ -std=gnu++11 ./source_file.cpp You may also try the clang compiler, as it has better c++11 support than g++. ...

I would upgrade to 14.04.1 LTS first as this may have some of the hardware support updates included; After updating I would then check to see if the hardware support updates are still available. This is my personal preference based on potentially saving some time although it shouldn’t make much difference as to what order you select to do it in! The ...

The one of following command lines which one you should install using the terminal: 14.04: sudo apt-get install libegl1-mesa-drivers 14.10: sudo apt-get install libegl1-mesa-drivers-lts-utopic It will remove and update some programs automatically. Then, you yourself can install QT Creator w/o removing some programs you do not want. No Sweat! Vote ...

I had to manually free up space in boot. Since apt-get was useless, I had to manually remove the files for the 2 oldest linux kernels. This is an example of what I ran to remove a single kernel.

14.04.2 is only a version for the image release. The version of Ubuntu itself is still 14.04. The appended numbers on LTS versions are simply later image milestone releases, to differentiate them from the original installer images. If you've installed all the updates, then you have the same packages as are on the 14.04.2 image already. If you need the HWE ...

14.04 works perfectly after upgrading by option offered in update menu of previous 12.04.5. Been watching terminal closely during the installation, there were some warnings about possible problems, but after rebooting only pre-existing i-sight missing firmware problem was reported, which suits me even better, haha. Everything else works just fine, as for ...
