Does upgrading Ubuntu kernel change its release name?
Solution 1:
Ubuntu releases and the kernel versions are independent from each other.
Open a terminal and check the Ubuntu release version with this command :
lsb_release -a
The output shows something like :
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 15.10
Release: 15.10
Codename: wily
Open a terminal and check the running kernel version with this command :
uname -r
The output shows something like :
4.2.0-22-generic
This was a PC running Ubuntu 15.10 - here is a PC running Ubuntu 14.04 :
If you opt into the hardware enablement stack for Ubuntu 14.04 (Trusty),
the outputs will show that the release still is 14.04 and the kernel is 3.19.
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty
uname -r
3.19.0-42-generic
Solution 2:
Upgrading your LTS release to a newer kernel line does not change the release name.
So you still have Ubuntu 14.04 trusty.
See about HWE
LTS releases allow to install kernels from non-LTS main releases.
linux-generic-lts-wily
installs the kernel from 15.10 "wily" release.
It will be default in Ubuntu 14.04.4.
This may be a bit confusing.
