Conference in Culhuacán IPN
Between Ubuntu automatic updates from time to time we proposed to install a new version of the kernel. There is the possibility of compiling the kernel, optimizing it for our system, or use the precompiled kernel, automatically installing Ubuntu when we propose it. When you install a new kernel from the "Update Manager", the previous version remains in the system. The new kernel will appear between the grub boot options. If you have configured the system to start using an option listed as "default", incorporating a new kernel can lead to unexpected situations, it may alter the serial number of the boot options in grub menu. Apart from this minor inconvenience, the kernel also takes up some space on your hard disk, so it may be interesting to eliminate the unused versions. To remove an old kernel can take the following steps: verify the versions available on your system: sudo dpkg-l released them in the order of 90 MB. Negligible.
