Uhlaziyo lwe-Ubuntu 18.04.4 LTS sele ikhutshiwe, yazi iindaba zayo

Njengenxalenye yomjikelo wohlaziyo olufumanekayo uguqulelo oluxhaswe ixesha elide loBuntu, ICanonical ibhengeze ukukhutshwa kohlaziyo lwesine lwenguqulo ye-Ubuntu 18.04 LTS okubandakanya utshintsho olunxulumene nokuphucula inkxaso yehardware, ukuhlaziya i-kernel ye-Linux kunye nokufakwa kwemizobo, ukulungisa iibugs kwi-installer nakwi-bootloader.

ngaphandle koko Ukwakhiwa kukwabandakanya uhlaziyo lweephakeji ezilikhulu inxulumene nokulungisa ukuba semngciphekweni kunye nemiba echaphazela uzinzo. Kunye nolu hlaziyo, ezo zihambelana neencasa zazo ezisemthethweni zikwaziswa kwangaxeshanye, ezi: Kubuntu 18.04.4 LTS, Ubuntu Budgie 18.04.4 LTS, Ubuntu MATE 18.04.4 LTS, Lubuntu 18.04.4 LTS, Ubuntu Kylin I-18.04.4 LTS kunye ne-Xubuntu 18.04.4 LTS.

Yintoni entsha ku-Ubuntu 18.04.4 LTS?

Ngokukhutshwa kolu hlaziyo, uhlaziyo lweephakeji kunye i-kernel 5.3, Kunye nezinto ezihlaziyiweyo zokubekwa kwemizobo, kubandakanya neenguqulelo ezintsha ze Itheyibhile 19.2, X.Org Server 1.20.5, kunye libdrm 2.44.99, ezavavanywa kwi-Ubuntu 19.10.

Kwakhona Abaqhubi bevidiyo abatsha be-Intel, i-AMD kunye ne-NVIDIA chips bongeziwe (kubandakanya i-NVIDIA 435 yokuqhuba umqhubi), iiphakheji ezihlaziyiweyo OpenJDK 11 (I-OpenJDK 8 isiwe kwindawo yokugcina izinto), I-OpenSSL 1.1.1 (I-OpenSSL 1.0.2n), thunderbird 68.2.2, dpdk 17.11.6, snapd 2.42, cloud-init 19.4.33, open -vm-tools 11.0, openvswitch 2.9.5.

Olunye utshintsho olukhankanyiweyo kolu hlaziyo kukuba yongeze inkxaso yokuzama ukuzama i-boot kwimeko yokusilela kwisixhobo se-plugin kwaye ndongeze iphakheji ye-wslu ngoqwalaselo kunye nezixhobo zokudibanisa Ubuntu kunye ne-WSL (Windows Subsystem yeLinux) indalo.

Ngelixa leGnome, iindidi zezicelo ezifumanekayo kulawulo lwephakheji zahlaziywa kwifomathi yangoko.

Kwidesktop eyakhayo, i-kernel entsha kunye nokufakwa kwemizobo kucetyiswa ngokungagqibekanga. Kwiinkqubo zeseva (Ubuntu Server), i-kernel entsha yongezwa njengenketho kwisifaki.

Olunye utshintsho olume ngaphandle kwi-Ubuntu 18.04.4 LTS:

• Inkonzo yokugqibela yongeziwe kulwakhiwo, ukuvumela imixholo yolawulo / run / initramfs ukuba yenziwe, eya kuthi isetyenziswe kwinkqubo-yokuvala inkqubo kwinkqubo yokuvala inkqubo xa isahlulelo seengcambu sesingathotywa;
• Kwi-shiftfs, i-FS ebonakalayo yokwenza imephu yomsebenzisi we-namespace mount points ifumene inkxaso ye-I / O ethe ngqo (O_DIRECT, sebenza ngaphandle kokubhaqa kunye nokudlula kwi-cache).
• The ubuntu-web-launchers package isuswe kuluhlu lwezicelo ezicetyiswayo;
• KwiThunderbird, yokutshintsha iifayile kwimowudi yeFayileLink, apho uncamathiselo sigcinwa khona kwiinkonzo zangaphandle ezinamakhonkco kuphela adluliselwe kugcino lwangaphandle njengenxalenye yomyalezo, inkonzo ye-WeTransfer isetyenziswa ngokungagqibekanga.

Ukuhanjiswa kwezi nguqulelo zintsha I-kernel kunye ne-graph stack, isetyenziswe kwimodeli yenkxaso yokuhlaziya eqhubekayo ngokokutsho, iinkozo ezifakwayo kunye nabaqhubi ziya kuxhaswa kuphela kude kube luhlaziyo olulandelayo lokuhlaziywa kwesebe Ubuntu 18.04 LTS.

Umzekelo, i-Linux 5.3 kernel ecetywayo kwinguqulelo yangoku iya kuhambelana nohlobo lwe-Ubuntu 18.04.5 (eya kuthi ibonelele nge-Ubuntu 20.04 kernel). Ngelixa eyona Ubuntu 18.04 LTS Kernel (4.15) ihanjiswa ekuqaleni iya kuxhaswa kumjikelo wolondolozo.

Inkxaso yenguqulo ye-LTS ye-Ubuntu 18.04 iya kuhlala kude kube ngu-Epreli 2023, emva koko kuya kuveliswa olunye uhlaziyo lweminyaka emi-5 njengenxalenye yenkxaso eyahlukileyo ehlawulelweyo (i-ESM, uLondolozo loKhuseleko oluNgezelelweyo).

Ungayihlaziya njani Ubuntu 18.04.4 LTS?

Kulabo banomdla wokukwazi ukufumana uhlaziyo lwenguqulelo entsha, banokudlulisa ufakelo lwabo olukhoyo kwiinguqulelo ezintsha zekernel kunye nokufakwa kwemizobo, ngokwenza lo mthetho ulandelayo:

sudo apt-get install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

Ukuba awunafakelo lwangaphambili lwe-Ubuntu 18.04 LTS, unokufumana umfanekiso wenkqubo ngokuya kwiwebhusayithi esemthethweni Ubuntu.
