Ukuvuselelwa kwenguqulo ye-Ubuntu LTS 20.04.1, 18.04.5 kanye ne-16.04.7 sekukhishiwe

Ukwethulwa kwe-Canonical Zimbalwa izinsuku ezedlule kukhishwa ngezibuyekezo izinhlobo ezahlukahlukene ze-LTS zohlelo lwayo lokusebenza "Ubuntu" futhi kulokhu kuyisimo senguqulo yokuqala ye- Ubuntu 20.04.1 LTS, ngenkathi yenguqulo 18.04 isibuyekezo sokususa esitholiwe nango-16.04 ingeyesikhombisa.

Endabeni yalezi ezimbili zokugcina, kwethulwa izibuyekezo ezahlukahlukene yamaphakeji akha uhlelo, kanye ne ukufakwa kwezinguqulo ezintsha ze-Linux kernel, isitaki sehluzo nokuningingenkathi yenguqulo 16.04 kuphela ukulungiswa kwamaphutha kufakiwe kanye nezixazululo zezinkinga ezihlukaniswe njengezimbi.

Ubuntu 20.04.1

Isibuyekezo esisha ifaka izibuyekezo kumaphakeji angamakhulu amaningana ukubhekana nobuthakathaka nezinkinga zokuqina. Le nguqulo entsha iphinde ilungise izimbungulu kufaki naku-bootloader.

Ukukhishwa kwe-Ubuntu 20.04.1 kumake ukuzinza okuyisisekelo kokukhishwa kwe-LTS.

Izinguquko eziphawuleka kakhulu zifaka:

• Ukulungiswa kokusebenza kwenziwe. Ukuxhaswa kwe-AES-GCM hardware kusetshenziselwe i-zfs-linux.
• Isikhungo Sokulawula se-GNOME sinengxoxo yokuqinisekisa iminwe eyenziwe kabusha.
• Kungezwe ukwesekwa kwe-VPN Wireguard.
• I-Linux kernel yokuthunyelwa kwe-OEM ibuyekezelwe ku-5.6 (Ubuntu 20.04 imikhumbi ene-5.4).
• Kungezwe usekelo lokuthulisa i-LED yamabhuku ezincwadi amasha we-HP.
• Kungezwe ukusekelwa kochungechunge lweseva yokushayela yomnikazi we-NVIDIA.
• Isifaki sifaka ukusekelwa kwe-ZFS autotrim. I-Live-build ingeza ukwesekwa kwe-riscv64.
• Izinhlobo ezibuyekeziwe ze-libreoffice (6.4.4), i-GNOME (3.36.2), snapd, evince, golang-1.14, curtin, nautilus, gedit, gnome-control-center, evolution-data-server, mutter, gnome-software package , shotwell, netplan.io, OpenStack Ussuri, cloud-init, open-vm-tools, gtk + 3.0, ceph, sosreport, libgphoto2.
• Ukuhlanganiswa kwe-kernel entsha, abashayeli, nezakhi zesitaki sehluzo kulindeleke ukuthi kukhishwe ngoFebhuwari 20.04.2, njengoba lezi zinto zizongeniswa zisuka ekukhishweni kwe-Ubuntu 20.10, ezingeke zitholakale kuze kube ukuwa futhi zizodinga isikhathi esengeziwe sokuhlola. .

Ubuntu 18.04.5 LTS

Ngale nguqulo, lesi isibuyekezo sokugcina esifaka phakathi izinguquko zokuthuthukisa ukwesekwa kwehardware, buyekeza i-Linux kernel ne-stack stack bese ulungisa amaphutha wesifaki ne-bootloader.

Njengoba ngokuzayo, izibuyekezo zegatsha le-18.04 zizokhawulelwa ekususeni ukuba sengozini nezinkinga ezithinta ukuzinza. Ngasikhathi sinye, kwethulwa izibuyekezo ezifanayo zeKubuntu 18.04.5 LTS, Ubuntu Budgie 18.04.5 LTS, Ubuntu MATE 18.04.5 LTS, Lubuntu 18.04.5 LTS, Ubuntu Kylin 18.04.5 LTS, neXubuntu 18.04.5 LTS.

Uhlobo olusha lunikeza izibuyekezo zephakeji nge-kernel 5.4 (Ubuntu 18.04 kernel 4.15 no-Ubuntu 18.04.4 kernel 5.3 esetshenzisiwe.

Izinto zesitaki sezithombe zibuyekeziwe, kufaka phakathi izinhlobo ezintsha ze- IMesa 20.0, i-X.Org Server ifakwe ku-Ubuntu 20.04 nabashayeli bevidiyo bama-Intel, AMD ne-NVIDIA chips.

Kungezwe ukusekelwa kokuhlukahluka kwebhodi yeRaspberry Pi 4 nge-8GB RAM. Izinhlobo ezibuyekeziwe ze-snapd, curtin, ceph, cloud-init package.

Ukukhishwa kwe-Ubuntu 18.04.5 kuthengiswa njengokukhishwa kwenguquko futhi kufaka phakathi izinto zokuthuthukela ku-Ubuntu 20.04.1.

Kunengqondo ukusebenzisa inguqulo entsha eyethulwe ukufakwa okusha kuphela, kepha ezinhlelweni ezintsha ukukhishwa kwe-Ubuntu 20.04.1 LTS kusebenza kakhulu, esivele sidlulile isigaba sokuqala sokuzinza ngemuva kokwethulwa kwegatsha elisha le-LTS.

Amasistimu afakwe phambilini angathola zonke izinguquko ezikhona ku-Ubuntu 18.04.5 ngohlelo olujwayelekile lokufaka isibuyekezo.

Ukusekelwa kokukhishwa kwezibuyekezo nokulungiswa kokuphepha kwama-server kanye nama-desktop editions we Ubuntu 18.04 LTS izohlala kuze kube ngu-Ephreli 2023, ngemuva kwalokho kuzokwakhiwa izibuyekezo ngaphansi kohlaka lokuxhaswa olukhokhelwayo oluhlukile (i-ESM, i-Extended Security Maintenance) eminye iminyaka emi-5.

Ubuntu 16.04.7 LTS

Ekugcineni kwaleli gatsha, isibuyekezo esifaka kuphela izibuyekezo zephakeji eziqoqekayo ezihlobene nokususwa kobungozi nezinkinga ezithinta ukuzinza.

Inhloso enkulu yenguqulo entsha ukuvuselela izithombe zokufaka. Njengakwinguqulo yangaphambilini, Ama-Linux kernels 4.15 no-4.4 ahlinzekwa, kanye neMesa, X.Org Server ethwelwe kusuka ku-Ubuntu 18.04 nabashayeli bevidiyo bama-Intel, AMD ne-NVIDIA chips.

Ukusekelwa kokukhishwa kwezibuyekezo nokulungiswa kokuphepha kwama-desktop kanye nama-server editions Ubuntu 16.04 LTS izohlala kuze kube ngu-Ephreli 2021.
