getting disk error after updates were downloaded
I'm using Ubuntu 8.04 and have absolutely no problems with it until a few weeks ago. I turned it on and it said I had updates so I clicked on the icon for the updates and it started updating 200+ updates. Ever since then, when I start it up it takes twice as long and then I get an error message telling me that "100% of disk space on the root partition is in use." Then it will slowly load the rest of the startup programs. When I try to click on the web it flickers and I can make out that it's looking to see if the updated add-ons are compatible. Then I get an error message from mozilla (my default browser) telling me that either "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." or "404: File not Found. /projects/firefox/3.0.10/firstrun We are sorry, the file you requested could not be found." But a second tab for Yahoo (my default page) still comes up. I will close out the Firefox error message tab and can fully use the internet with no problems. Then the last thing that is now happening is when I shut down. It won't shut down unless I hold down the on/off button.
So my question is...is this fixable? Has anyone else experienced any of this and how did you fix it? Or do I need to just reinstall from scratch?
I appreciate any help. Thanks.
