did you check the md5sum on the ISO file? However, if you got a bad ISO file to make the DVD, that could be the source of the trouble. If you booted on an Ubuntu live DVD to started this upgrade, you may be able to boot it again and start from scratch. I hope you have another means to get on the Internet to get whatever tools and/or advice that you will need to get things working again. Whatever steps you take next, it may be that the laptop won't boot. but in the middle of an installation it seems like this will also end badly. If the laptop is still responsive, you may can open a terminal and stop the process that is hung. You will probably have to cancel (if it will) and you may have to just power it down (which is a terrible choice).

once its hung up, it will probably stay hung up. Letting it continue to try is not likely to work. you may or may not have even needed that on your system, but that doesn't matter now. Ubuntu is definitely a fine distro and I'm sure there is a solution to your problem. All of these many variants dump the Unity Launcher.īut switching distros can be a big deal if you aren't used to it, so maybe the other suggestions will help you get over the current hurdle. There are also other Ubuntu flavors that would do the same: Lubuntu, Xubuntu, or Ubuntu Mate, for example. These other distros would put the 'panel' (and launcher icons) at the top or bottom of your screen. LXLE is another distro with easy hardware requirements and is Ubuntu-based. I am currently using Linux Lite and it is also extremely capable and Ubuntu-based, and it is easy on hardware requirements. I used Mint for many years and it is outstanding. The Unity Launcher is one of the main gripes about Ubuntu, but of course it is an excellent distro for the most part, which is why so many others use it as a base. Another option that is somewhat more involved would be to dump Ubuntu and give Linux Mint a go instead (or other Ubuntu-based distros). Another way to switch between open programs is to use Alt-Tab. But have you tried the 'Super Key' (Windows Logo key)? In many distros that will bring up the Menu, although that may be a different menu than the Unity Launcher. I don't know if a software update would change things like this.
