ubuntu中卸载emacs时出错

Question

I am new to Linux and using Ubuntu. I was trying to add the sage math mode in emacs. I did something wrong while editing the site-start.el file in ~/.emacs folder and emacs started to do some funny things. By mistake I deleted the emacs folder in ~/etc in which I did the editing. Now whenever I in am trying to uninstall emacs. I am getting the following error message. Can some help me out on this. Thanks Anil

Answer 1

Well, the error being reported is this...

cp: cannot stat `/etc/emacs/site-start.d/00debian-vars.el': No such file or di

which from what you say, you deleted by hand (as far as I can tell -- your report is not very precise, so there is some guess work going on.

You could try reinstalling emacs first and then uninstalling. Or something like

apt-get remove --force emacs23

In general, you don't want to be deleting files in /etc by hand; it's better to let apt do this for you.

Answer 2

Finally did it by fooling the error. Just added the said directories and files which were giving error. The uninstallation script needs the physical files and directory paths. So simply adding the paths does the trick.
