This is a rather general question, but I'd really like to know where I got it wrong. Less than a year ago on one of my laptops, I installed Ubuntu 12.04 precise (Kernel 3.8.x) Now I am told that HWE support is running out and I have to manually install trusty components. How does this combine with "LTS". Especially as there are discussions that this update is not as straight forwardnot as straight forward as the update instructions suggest.
So did I miss something in the small print in the first place? Note, if you are new to Ubuntu and get an LTS promise, you surely do not check the wiki on HWE, or care about kernel versions. (...now I do...)
