Hi,

After running an upgrade, I have problems with apt-get and I'm suspecting that it has to do with the upgrade of X to 4.3. I get tons of dependency errors (around 42 - what an D. Adams coincidence!), and I am recommended as usual to try -f. Then I get the following:

blues:/home/j_lo# apt-get -f install

Any help is much appreciated. Neither my X or apt-get is working properly at the moment :-(.

Thanks in advance1

try:

apt-get update
apt-get -f dist-upgrade

it will some packages to be installed but it won't. What it will do is reconfigure the packages. This is what i did yesterday.

hope this helps!

Thank you very much for your suggestion. All packages updates well, except this xlibmesa:

Use dpkg -i --force-overwrite /var/cache/apt/archives/xlibmesa-gl_4.3.0-7_i386.deb as root it will then overwrite the file from the other package which is holding it up and you will want to do a dpkg --configure -a as well to make sure that no packages were left unconfigured when the error occurred.

Hi, thanks for your answer. Now it looks like xlibmesa needs libxext6 and (or?) xlibs. Do you think I should try to install them in the same way, using -i --force-overwrite?

Problem solved :-)
