I recently upgraded my dedicated server to ubuntu 16.04 LTS (for somes reasons). I don't know why, but when I started my server, nothing happened (no ping response).
With my host, I can boot on a live cd image (ubuntu 12.04) to recorvery my server. So I mounted my partitions to do a chroot session and I navigated to my /var/log folder. In this folder, there is no news logs (like "boot.log" or "syslog" written when I start my server with Ubuntu 16.04. It's like the server don't boot. Maybe a Grub Config Bug ?
Ps: I recently had a problem with my image "/boot/vmlinuz-4.4.0-47-generic" (image was missing when I tried to apt-get -f upgrade) but I reinstalled a new one with apt-get, My kernel version :
Linux 62-210-243-90 3.13.0-32-generic #57~precise1-Ubuntu SMP Tue Jul 15 03:51:20 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Here is my Grub configuration :
# If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="console=ttyS1,9600 BOOTIF=01-e8-9a-8f-22-d9-61" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"
