Ubuntu 20.04 yinguqulelo ye-LTS ebonelela ngeminyaka emihlanu yenkxaso, kude kube ngu-Epreli ka-2021
Uhlaziyo olutsha lwe Ubuntu 20.04.5 LTS yayisele ikhutshwe kwiintsuku ezininzi ezidlulileyo kwaye ibandakanya utshintsho olunxulumene nenkxaso yehardware ephuculweyo, uhlaziyo kwi-Linux kernel kunye ne-graphics stack.
Olu hlaziyo lutsha lukhutshiwe, kubandakanya uhlaziyo lwamva nje lwamakhulu amaphakheji ukujongana nobuthathaka kunye nemiba yozinzo, kunye nokuhlaziywa okufanayo kukhutshwa Ubuntu Budgie 20.04.5 LTS, Kubuntu 20.04.5 LTS, Ubuntu MATE 20.04.5 LTS, Ubuntu Studio 20.04.5 LTS, Lubuntu 20.04.5 LTS, Ubuntu Kylin 20.04.5. 20.04.5 LTS kunye neXubuntu XNUMX LTS.
Le nguqulo yesihlanu izisa kunye lonke uhlaziyo lwesoftware epapashwe ukuza kuthi ga ngoku, kunye neendawo ezahlukeneyo zokhuseleko kunye nomsebenzi obanzi wokulungisa ibug.
Loluphi utshintsho oluvezwa ku-Ubuntu 20.04.5 LTS?
Olu hlaziyo lwenqaku lutsha lunikezelwe kule nguqulelo ye-LTS ye-Ubuntu kubandakanya ezinye izinto eziphuculweyo ezixhaswe okoko kukhutshwa Ubuntu 22.04, njengeephakheji ze-kernel 5.15 ngoku ezinikezelwayo (Ubuntu 20.04 isebenzisa i-kernel 5.4, 20.04.4 ikwabonelela nge-kernel 5.13).
Ngokungafaniyo ne-kernel 5.4 (eyi-kernel engagqibekanga ku-Ubuntu 20.04), I-Kernel 5.15 inikeza un umqhubi omtsha we-NTFS ngenkxaso yokubhala, imodyuli ye-ksmbd enokuphunyezwa kweseva ye-SMB, inkqubo esezantsi ye-DAMON yokubeka iliso kwimemori yokufikelela, itshixa izinto zokuqala zexesha lokwenyani, fs-ukunyaniseka kwenkxaso kwi-Btrfs
Ukwakhiwa kweDesktop (Ubuntu Desktop) ine-kernel entsha kunye ne-graphics stack ngokungagqibekanga. Kwiinkqubo zeseva (Iseva ye-Ubuntu), ikernel entsha yongezwa njengokhetho kwisifakeli.
Kwakhona, kubaqhubekisi be-Intel banamhlanje, baye bafumana umlawuli omtsha wokupholisa, Inkxaso yokuqala yanikezelwa kwiinkqubo ezintsha ezivela kulo mvelisi, ebizwa ngokuba yi-Alder Lake-S (isizukulwana se-12).
Kwicala lokuhlaziya amacandelo e-graphics stack, sinokuyifumana loo nto Abaqhubi be-Mesa 22.0 babandakanyiwe, eziye zavavanywa kwinguqulo ye-Ubuntu 22.04 kwaye apho iinguqulelo ezintsha zabaqhubi bevidiyo be-Intel, AMD kunye ne-NVIDIA chips zongezwa kwaye sinokufumanisa, umzekelo, ukuba abaqhubi. Intel GPUs yenziwe ngokungagqibekanga ukuxhasa i-Adaptive-Sync (VRR), ikuvumela ukuba utshintshe ngokuguquguqukayo ireyithi yokuhlaziya imonitha yakho yokuphuma egudileyo, ngaphandle kwe-stutter, kunye nenkxaso ye-API yemizobo ye-Vulkan 1.3.
Olunye utshintsho esinokulufumana lu iinguqulelo ezihlaziyiweyo ukusuka ceph package 15.2.16, PostgreSQL 12.10, ubuntu-advantage-izixhobo 27.10, openvswitch 2.13.8, modemmanager 1.18, cloud-init 22.2, snapd 2.55.5.
Gqibela Ukuba unomdla wokwazi okungakumbi ngayo, ungajonga iinkcukacha Kule khonkco ilandelayo.
Uhlaziya njani uhlaziyo olutsha lwe-Ubuntu 20.04.5 LTS?
Kulabo abanomdla kwaye bakwi-Ubuntu 20.04 LTS, banokuhlaziya inkqubo yabo kuhlaziyo olutsha olukhutshwe ngokulandela le miyalelo.
Kufanelekile ukuba ukhankanye loo nto ukusebenzisa ulwakhiwo olutsha kunengqiqo kufakelo olutsha-Iinkqubo ezifakwe ngaphambili zinokufumana zonke iinguqu ezikhoyo ku-Ubuntu 20.04.5 ngokusebenzisa inkqubo yokufakela uhlaziyo oluqhelekileyo.
Ngokungafaniyo nokukhutshwa kwe-LTS yangaphambili, iinguqulelo ezintsha ze-kernel kunye ne-graphics stack ziya kubandakanyeka kufakelo olukhoyo lwe-Ubuntu Desktop 20.04 ngokuzenzekelayo, kwaye azibonelelwa njengokhetho. Ukubuyela kwisiseko se-5.4 kernel, umyalelo kufuneka wenziwe:
sudo apt install --install-recomienda linux-generic
Ukuba bangabasebenzisi beDesktop ye-Ubuntu, vula nje itheminali kwinkqubo (banokuyenza ngonqamlezo Ctrl + Alt + T) kwaye kuyo baya kuchwetheza lo myalelo ulandelayo.
sudo apt update && sudo apt upgrade
Nje ukuba ugqibile ukukhuphela kunye nokufaka zonke iipakethi, nangona kungeyomfuneko, sincoma ukuqala kwakhona ikhompyuter yakho.
Ngoku kwabo bangabasebenzisi beserver Ubuntu, umyalelo ekufuneka bawuthayiphe ulandelayo:
sudo apt install --install-recommends linux-generic-hwe-20.04
Okokugqibela, ukuba unomdla wokufunda ngakumbi malunga nokukhutshwa kweLTS, ungajonga iinkcukacha Kule khonkco ilandelayo.
