Sineenguqulelo ezintsha zoBuntu qho emva kweenyanga ezintandathu, kodwa ezinkulu, apho zibeka yonke inyama kwigrill kunye nezona zizinzileyo, ziphume zibaliwe iminyaka ngo-Epreli. Abasebenzisi abakhetha iinguqulelo ze-LTS benza njalo kuba bafuna okanye bakhetha uzinzo, kodwa oku kunokuchaphazeleka ngokungalunganga ngohlaziyo lwekernel. Kuba, umzekelo, Ubuntu 20.04 yakhutshwa ngeLinux 5.4, kodwa ukusukela kwiveki ephelileyo ilayishwe kwiLinux 5.11.
I-Canonical ayenzi izinto ngendlela engeyiyo, kodwa ndicinga ukuba kufanele ibandakanye ukhetho "lokuphuma" ukuvumela abasebenzisi beenguqulelo ze-LTS Ubuntu ukuba bahlale kuhlobo lwe-LTS lwekernel. Ngokusesikweni, uthanda okanye ungathandi, Ubuntu buza kufaka i-kernel kuyo yonke indawo yokukhululwa, malunga neenyanga ezintandathu, kodwa unako Ndithintele ekuhlaziyeni i-kernel iye phezulu ukulandela la manyathelo.
Ubuntu 20.04 kunye nayiphi na inguqulelo ye-LTS ngaphandle kokufaka i-kernel
Ngaphambi kokuqhubeka, kufuneka icaciswe ukuba ukulandela la manyathelo akuyi kuyeka ukufumana inkxaso. I-kernel ye-LTS iya kuqhubeka nokuhlaziya, kodwa ukulungisa i-bugs. Into engazukuyenza kukuya kolunye uthotho, kwaye iya kuhlala igcinwe kwiLinux 5.4.x. Ngale nto ichaziweyo, into ekufuneka uyenzile kukuthatha la manyathelo mabini:
- Kuya kufuneka ususe i-HWE meta package (Ukusebenza kweHardware) ngalo myalelo, utshintsha «{umfanekiso, izihloko}» ngokubala izinto esifuna ukuzisusa (Uluhlu lwe-dpkg | grep linux-umfanekiso Kwisiphelo sendlela yokubabona bonke). Oku kufuneka kwenziwe ngako konke, ngaphandle kweLinux 5.4:
sudo apt remove linux-{image,headers}-generic-hwe-20.04
- Nje ukuba ezi phakheji zisuswe, kuya kufuneka ufake enye enesiqhelo:
sudo apt install linux-generic
Nje ukuba yenziwe, i-kernel iya kuhlaziywa, kodwa kwi-5.4.0.x eya kufumana uhlaziyo lokhuseleko.
Okungentla iyasebenza kulo naluphi na uhlobo lweLTS, kodwa kwixa elizayo "20.04" kuyakufuneka itshintshwe. Ngale ndlela, ukuba Ubuntu kunye ne-kernel yayo benza kakuhle kuthi ngalo mzuzu xa bekhupha uXwebhu lweNkxaso yeXesha elide, siya kuqinisekisa ukuba uhlaziyo lwekernel aluyonakalisi inkqubo.
