Ubuntu 20.04 is nowhere close to finish of life, however 22.04 is beginning to hit its stride.
As is pretty nicely understood now, the primary launch of Ubuntu in every even-numbered 12 months is a Lengthy Time period Help (LTS) release. Ubuntu 20.04 “Focal Fossa” will get assist and updates till 2025 and will not attain its official end-of-life till 2030. “Jammy Jellyfish” – the 22.04 launch – is the substitute LTS model, receiving mainstream assist till April 2027 and arriving at its finish of life in April 2032.
Nevertheless, customers of the earlier LTS launch do not begin to obtain improve notifications till the next LTS will get its first level launch. For Jammy, if all goes nicely, that needs to be right now: August 11 is the deliberate launch date for Ubuntu 22.04.1. Canonical has revealed a list of bug-fixes on its Discourse, and you may as well monitor its standing on Launchpad.
Amongst many others, 22.04.1 incorporates a repair for the latest speculative-executation flaw, Retbleed. This has led to hypothesis a couple of new regulation of laptop pace adjustments.
Nathan Froyd requested Twitter:
What is the reverse of Moore’s regulation, the place CPUs get 15 p.c slower yearly resulting from speculative-attack mitigations?
If you’re courageous, very cautious, and run a wholly standalone field, you may in fact choose to turn them all off.
As we stated once we looked at the 22.04 release, “Jammy” makes use of the latest LTS kernel, version 5.15. Many present customers of “Focal” could also be shocked to seek out that they have already got that, because it has already been distributed to customers of the Ubuntu LTS Enablement Stack, or HWE because it’s recognized for brief. The HWE stack features a new kernel and related drivers, and is a completely official, supported possibility.
This is without doubt one of the vital variations between Linux Mint and its upstream Ubuntu LTS launch: Mint does not use the HWE stack, though it is completely doable to manually set up it from Ubuntu’s repositories.
We coated how to install the HWE stack some six months in the past. At the moment, the present kernel for Focal was 5.14, so going to five.15 is a comparatively minor change, however it features a very helpful function when you dual-boot with Home windows, or recurrently join Home windows-formatted drives to your Ubuntu machine: native in-kernel read-write NTFS support.
When you at the moment mount NTFS drives utilizing the command
mount -t ntfs, as described on the primary web page of the kernel documentation for NTFS assist, you then’re nonetheless utilizing the older NTFS drivers. To make use of the brand new, in-kernel, version 3 driver, change it to
mount -t ntfs3. After all, when you’re mounting NTFS drives at boot time, this consists of altering the related traces in
/and many others/fstab.
You must see efficiency improvements, however The Reg FOSS desk has observed another adjustments, together with richer permissions assist – that means that beforehand writable folders on Home windows drives may not be any extra. We suggest the brand new driver, which is working nicely for us, however you must check any NTFS mounts for modified behaviour, together with permissions and possession, earlier than placing them into use. ®
