Izinqolobane ze-Ubuntu beziyisikhungo sokuphikisana Ubuntu ezinyangeni ezedlule. Ngemuva kwephutha elibucayi elivele njengomphumela we-Ubuntu 17.10 kernel, kuvele iphutha le-Specter neMeltdown. Isiphazamisi esenze Ubuntu kufanele sisuse izinhlobo zakamuva ze-microcode ye-Intel ukuze sinikeze ukuzinza nokuphepha ekusatshalalisweni.
Isikhathi sihambile, I-Intel ikwazile ukudala umshayeli ophephile noma i-microcode ye-Ubuntu yingakho Ubuntu banquma ukusebenzisana nayo ukuze banikeze isibuyekezo esivikelekile sazo zonke izinkundla zabasebenzisi baka-Ubuntu. Kuze kube manje, isixazululo besisezindaweni ezingamabhithi angu-64 kuphela. Ezinsukwini ngemva kokukhishwa kwaleso sibuyekezo, sesingakwazi kakade ukusho lokho. ukuvuselelwa kokuphepha kuyatholakala kuzo zonke izakhiwo ze-Ubuntu, ikakhulukazi ipulatifomu engama-32-bit, ipulatifomu abasebenzisi abaningi abasayisebenzisayo (ngaphandle kokuthi onjiniyela abaningi be-Ubuntu abayikholwa) nokuthi okwamanje bekungekho ukuvikelwa kulezi zinambuzane zokuphepha ezivumela ukudunwa komshini nge-kernel.
Lesi sibuyekezo sizovela kuwo wonke amahora ambalwa alandelayo we-Ubuntu 16.04 LTS, Ubuntu 17.10 ne-Ubuntu 14.04 LTS. Futhi ngokuya ngohlobo lokuxhumeka kwe-inthanethi esinakho nokusebenza kwamaseva we-Ubuntu. Kodwa-ke, uma sinokusatshalaliswa okungama-64-bit, lokhu kubuyekezwa kuzobe sekufikile ezinsukwini ezedlule. Kunoma ikuphi, ungahlala uzama ukusheshisa inqubo ngokuvula i-terminal bese uthayipha okulandelayo:
sudo apt-get update sudo apt-get dist-upgrade
Uma iphakethe litholakala ngempela, lizovela nale miyalo futhi lizosibuza ukuthi sifuna ukuyifaka noma cha. Kulokhu sizothi yebo selokhu iphakethe elizofakwa akulona nje noma yiluphi uhlelo kepha libizwa ngokuthi yi-security patch okuzokwenza ngcono ukuphepha kokusatshalaliswa.
Ngisukile ekusatshalalisweni okungu-16.04 (ebivele inezinkinga ngezikhathi ezithile ngomshayeli wehluzo le-Intel) ngaya ku-18.04 futhi manje lokhu kuye kwaba kubi kangangoba ngivame ukusebenza ngisebenzisa i-nomoset ku-grub ukuze ngiyivule.
