So,the WiFi driver on my system has a memory leak problem, known for a while. I'm running on 18.04.2 with HWE pack ergo Linux Kernel 4.18.

Since memory leak issue is fixed in 4.20 or next version (5.0 ?), I wanted to know whether/when will it be available, because I either can wait for a while or get a USB WiFi adapter. But even though point release is scheduled on 1st August, 2019, the point release page on ubuntu.com is not set up and I've not seen any announcements as such popup in google search, so I'm not sure what's new in 18.04.3. Any leads are appreciated.

  • Why not install 4.20? It is pretty easy to do. UKUU made it very easy omgubuntu.co.uk/2017/02/… – Rinzwind Jul 13 at 4:38
  • I can definitely try but I am skeptical as I've not used this application and would prefer to get official software. – lawki Jul 13 at 21:04
  • Oh, I got a new system a couple of weeks ago and have couple of keys that are not supported. installing kernel 5.1 was a matter of seconds with UKUU. and a matter of seconds removing it . It is absolutely brilliantly simple to do. – Rinzwind Jul 13 at 21:11

The best place to track such things is probably Launchpad. For 18.04 (Bionic Beaver), see Bionic (18.04) : Ubuntu. In the third point release, 19.04's kernel, i.e. 5.0, will be available via HWE. I'm not sure about the memory leak issue but at this point of time 3 bugs are targeted (See ubuntu-18.04.3 : Ubuntu). As the time passes, new bugs/issues would be reported and you might see increase in targeted bugs, i.e. bugs to be fixed. So, it's hard to interpret what exactly is coming with third point release as of now.


Kernel version 5.0 is available in the official repositories, to install recent version use:

sudo apt install linux-headers-5.0.0-20 linux-headers-5.0.0-20-generic linux-modules-5.0.0-20-generic linux-image-5.0.0-20-generic
  • Thanks, will try that. Are there issues/caveats that I should be aware of before trying this? – lawki Jul 13 at 21:08
  • @lawki I have 5.0.0-16 running at the moment and it works great. The caveat is that you manually have to upgrade to newer kernels, it's not auto-updated like the standard kernel. That's why I'm still with 5.0.0-16. – mook765 Jul 13 at 21:19
