If you’re using 10.10 there is no more “Software Sources” in your menu, even though it is referred to in some of the documentation. That said, the Ubuntu documentation web pages should have everything you need to know in a pretty understandable format.Ī quick note: I assume you’re using Ubuntu 10.04. Then again, there’s stuff that some guy made in his basement for himself and a couple of friends. There are many useful repositories, such as to get the latest Nvidia drivers or the current stable release of Pidgin. On Launchpad there is not only updates to stable releases, but also beta and alpha software, and even stuff that doesn’t quite work at all yet. Just because a person signs the Code of Conduct doesn’t mean they know what they’re doing. Keep in mind that anyone can create a PPA, even you. If package A requires a modified version of ffmpeg, and package B in a different repository requires a modified version of ffmpeg too, well, now there’s a good chance you might not be able to watch videos, for example, with package A or B or at all. Usually the worry for me is not malicious intent, but conflicting packages. Most likely you’ll use Launchpad for the majority of your PPA needs, but even so it can be dangerous to your computer. It’s too much to explain here, so I will point you to some worthwhile documentation. I have run into problems here and there, but generally speaking, PPA’s are the only way to get your software updated in Ubuntu between distro releases (don’t get me into a rant about that). It’s all very simple once you get the hang of it.
These packages are recommended, but optional, for the installation of gcc-4.8. You will also be prompted to install a number of suggested packages. Sudo update-alternatives -install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50 To add the PPA to your system, open a terminal( Ctrl+ Alt+ t) and run the following commands: sudo add-apt-repository ppa:ubuntu-toolchain-r/test
However, it appears that Launchpad does have a PPA available for the toolchain test builds that does include gcc-4.8, here: According to the changelog and package list, there are debs for i386, amd64, arm, and powerpc. The announcement for the release of gcc-4.8 was made on March 22nd, so you probably won’t be seeing this in an official repository just yet. Gcc-4.8 is currently available for 12.04(Precise) via the toolchain PPA or by compiling the source. Sudo apt-get install gcc-4.8 (unable to locate package) I tried the following commands without success: sudo apt-get install gcc (gcc is already the newest version)
