I mount /tmp with nodev, nosuid, and noexec options to increase the security of my Linux based web server. And, whenever I ran apt-get install or apt-get upgrade command, I am getting the following error:

Generating grub.cfg ...

How do I fix this problem without compromising security of the data or web-server?

Ubuntu Linux: Install vim Text Editor

Posted on in Categories , , last updated March 21, 2016

I recently switched from OS X to Ubuntu. When I run the ‘vim file.c’ command at terminal, I see an error message that read as follows:

The program ‘vim’ can be found in the following packages:
* vim
* vim-gnome

* vim-tiny
* vim-athena
* vim-gtk
* vim-nox
Try: apt-get install <selected package>

How do I fix this problem and why vim is not a default text editor on Ubuntu Linux? How can I install full-fledged vim text editor in Ubuntu Linux?
