How to install a lower version kernel in an Azure Ubuntu 16.04 virtual machine
This article is about how the Azure Ubuntu 16.04 virtual machine installs an earlier version of the kernel. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
The problem scenario is that the system kernel version installed using the platform image is Linux 4.15.0-1052-azure, but the customer environment requires Linux 4.15.0-1045-azure.
1, try the following (be sure to back up the virtual machine or take a snapshot of the disk before operation) to install the Ubuntu 4.15.0-1045-azure kernel:
# apt-get install-y linux-azure*-4.15.0-1045
# apt-get install-y linux-image-4.15.0-1045-azure
# apt-get install-y linux-tools-4.15.0-1045-azure
2, and then use the command to check to see if there is a 1045 kernel version of the file output, as shown below:
Root@leoubuntu1604b:~# grep menuentry / boot/grub/grub.cfg
If [x "${feature_menuentry_id}" = xy]; then
Menuentry_id_option= "--id"
Menuentry_id_option= ""
Export menuentry_id_option
Menuentry 'Ubuntu'-- class ubuntu-- class gnu-linux-- class gnu--class os $menuentry_id_option' gnulinux-simple-8716e09d-0f3d-47c5-a89a-666b9d0bd1bf' {
Submenu 'Advanced options for Ubuntu' $menuentry_id_option' gnulinux-advanced-8716e09d-0f3d-47c5-a89a-666b9d0bd1bf' {
Menuentry'Ubuntu, with Linux 4.15.0-1052Muzazure`-- class ubuntu-- class gnu-linux-- class gnu--class os $menuentry_id_option 'gnulinux-4.15.0-1052KuazureMill 8716e09dMui 0f3dMui 47c5Mui a89aMuth666b9d0bd1bf' {

3. After confirming that the output in 2 is correct, modify the "GRUB_DEFAULT" entry in the / etc/default/grub file as follows:
GRUB_DEFAULT= "Advanced options for Ubuntu > Ubuntu, with Linux 4.15.0-1045-azure"
4. After executing the "update-grub" command, restart the operating system and observe whether the version of the virtual machine has changed.
