Ubuntu 20.04 ukukhululwa kwe-LTS okunikeza iminyaka emihlanu yokusekelwa, kuze kube ngu-Ephreli 2021
Ukuvuselelwa okusha kwe I-Ubuntu 20.04.5 LTS yayisivele ikhishwe ezinsukwini ezimbalwa ezedlule futhi ihlanganisa izinguquko ezihlobene nokusekelwa kwehadiwe okuthuthukisiwe, izibuyekezo ze-Linux kernel, kanye nesitaki sezithombe.
Lesi sibuyekezo esisha sikhishwe, ifaka izibuyekezo zakamuva zamaphakeji angamakhulu amaningana ukubhekana nezingqinamba nezinkinga zokuzinza, kanye nokuvuselelwa okufanayo kukhishwa ku-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 neXubuntu XNUMX LTS.
Leli phuzu lenguqulo yesihlanu lihlanganisa ndawonye zonke izibuyekezo zesofthiwe ezishicilelwe kuze kube manje, kanye neziqephu ezihlukahlukene zokuphepha nomsebenzi omkhulu wokulungisa iziphazamisi.
Yiziphi izinguquko ezethulwa ku-Ubuntu 20.04.5 LTS?
Lesi sibuyekezo esisha sephoyinti sethulwe kule nguqulo ye-LTS ye-Ubuntu kufaka phakathi ezinye izithuthukisi ezisekelwayo kusukela kukhishwe Ubuntu 22.04, njengalawo amaphakheji e-kernel 5.15 manje anikezwa (Ubuntu 20.04 isebenzisa i-kernel 5.4, 20.04.4 futhi inikeza i-kernel 5.13).
Ngokungafani ne-kernel 5.4 (okuyi-kernel ezenzakalelayo ku-Ubuntu 20.04), I-Kernel 5.15 inikeza un umshayeli omusha we-NTFS onokusekela kokubhala, imojula ye-ksmbd enokuqaliswa kweseva ye-SMB, uhlelo olungaphansi lwe-DAMON lokuqapha ukufinyelela kwenkumbulo, ukukhiya okokuqala kwemodi yesikhathi sangempela, fs-verity support kuma-Btrfs
Ukwakhiwa kwedeskithophu (Ubuntu Desktop) kune-kernel entsha nesitaki sezithombe ngokuzenzakalelayo. Okwezinhlelo zeseva (Ubuntu Server), i-kernel entsha yengezwa njengenketho kusifaki.
Futhi, Kumaprosesa wesimanje e-Intel, isilawuli esisha sokupholisa sitholiwe, Ukuxhaswa kokuqala kwanikezwa nezinhlelo ezintsha zalo mkhiqizi, uphawu lwe-Alder Lake-S (isizukulwane se-12).
Engxenyeni yokubuyekeza izingxenye zesitaki sezithombe, singakuthola lokho Abashayeli be-Mesa 22.0 bafakiwe, ezivivinywe ku-Ubuntu 22.04 version nalapho izinguqulo ezintsha zabashayeli bevidiyo be-Intel, AMD kanye ne-NVIDIA chips zengeziwe futhi singathola, isibonelo, ukuthi abashayeli Ama-Intel GPU anikwe amandla ngokuzenzakalela ukuze asekele i-Adaptive-Sync (I-VRR), ikuvumela ukuthi uguqule ngokuguquguqukayo izinga lokuvuselela lomqaphi wakho ukuze uthole okukhiphayo okubushelelezi, okunganakiyo, kanye nokusekelwa kwe-API yezithombe ze-Vulkan 1.3.
Ezinye izinguquko esingazithola yilezi izinhlobo ezibuyekeziwe kusuka kuphakheji ceph 15.2.16, PostgreSQL 12.10, ubuntu-advantage-tools 27.10, openvswitch 2.13.8, modemmanager 1.18, cloud-init 22.2, snapd 2.55.5.
Okokugcina Uma unesifiso sokwazi okwengeziwe ngakho, ungabheka imininingwane Kulesi sixhumanisi esilandelayo.
Ungayibuyekeza kanjani isibuyekezo esisha se-Ubuntu 20.04.5 LTS?
Kulabo abanentshisekelo futhi abaku-Ubuntu 20.04 LTS, bangavuselela isistimu yabo kusibuyekezo esisha esikhishwe ngokulandela le miyalo.
Kuyafaneleka ukusho lokho ukusebenzisa ukwakha okusha kwenza umqondo ekufakweni okusha- Amasistimu afakwe ngaphambilini angathola zonke izinguquko ezikhona ku-Ubuntu 20.04.5 ngohlelo olujwayelekile lokufakwa kokuvuselela.
Ngokungafani nokukhishwa kwangaphambilini kwe-LTS, ukukhishwa okusha kwe-kernel kanye ne-graphics stack kuzobandakanyeka ekufakweni okukhona kwe-Ubuntu Desktop 20.04 ngokuzenzakalelayo, futhi akunikezwa njengezinketho. Ukuze ubuyele ku-base 5.4 kernel, sebenzisa umyalo:
sudo apt install --install-recomienda linux-generic
Uma bengabasebenzisi be-Ubuntu Desktop, vele uvule ukuphela kohlelo (bangakwenza ngesinqamuleli esithi Ctrl + Alt + T) futhi kuyo bazothayipha umyalo olandelayo.
sudo apt update && sudo apt upgrade
Ekupheleni kokulanda nokufakwa kwawo wonke amaphakheji, nakuba kungenasidingo, sincoma ukuthi uqale kabusha ikhompuyutha.
Manje kulabo abangabasebenzisi be-server ye-Ubuntu, umyalo okufanele bawuthayiphe ulandelayo:
sudo apt install --install-recommends linux-generic-hwe-20.04
Okokugcina, uma ungathanda ukwazi okwengeziwe ngalokhu kukhishwa kwe-LTS, ungabheka imininingwane Kulesi sixhumanisi esilandelayo.
