Nakulokhu futhi, iCanonical inayo kubuyekezwe i-Ubuntu kernel nawo wonke ama-flavour asemthethweni futhi futhi ukwenzile ukuxazulula izinkinga zokuphepha. Ku- eminye imibuthanoInkampani eqhuba uMark Shuttleworth ilungise izimbungulu eziningi kangangokuthi siphathe lesi sibuyekezo ngokuthi "siyaphuthuma", kodwa kulokhu kube khona ukukhubazeka okumbalwa okulungisiwe futhi akekho noyedwa wabo obucayi ngokwanele ukuthi angakhathazeka kakhulu; akukho okuphuthumayo okuphezulu noma okugxekayo.
I-Los Izinhlelo ezithintekile yizo zonke lezo ezijabulela ukwesekwa okusemthethweni, okumanje yi-Ubuntu 19.10 Eoan Ermine, Ubuntu 18.04 Bionic Beaver ne-Ubuntu 16.04 Xenial Xerus. Ngesikhathi sokubhala le ndatshana, akukho lwazi olushicilelwe mayelana ne-Ubuntu 14.04, njengamanje esigabeni se-ESM, noma i-Ubuntu 20.04, inguqulo okwamanje esathuthukiswayo ezokwethulwa ngokusemthethweni ngo-Ephreli 23. Ubuntu 12.04 ayisasekelwa (ngisho nase-ESM) kanti Ubuntu 19.04 ifinyelele ekupheleni komjikelezo wayo wokuphila ngoLwesine olwedlule.
I-Ubuntu 16.04 kernel iyona ethinteka kakhulu, inobuthakathaka obungu-9
Imibiko esitshela ngezinambuzane zokuphepha ezilungisiwe yilezi I-USN-4253-1, esisitshela ngobungozi ku-Eoan Ermine, the I-USN-4255-1, esisitshela ngokukhubazeka okubili ku-Bionic Beaver, kanye ne- I-USN-4254-1, eyenza okufanayo kodwa mayelana 9 Xenial Xerus ukuba sengozini. Zonke izimbungulu zango-19.10 no-18.04 zinokuphuthuma okuphakathi, ngenkathi ngo-16.04 2 wokuphuthuma okuphakathi zilungisiwe kanti zonke ezinye zibaluleke kakhulu noma azinakwa. Izimbungulu zazingasetshenziselwa ukuveza imininingwane ebucayi, kepha ukufinyelela kwendawo kuleyo mishini kwakudingeka.
Njengakwezinye izikhathi, iCanonical ishicilela kuphela imibiko yezokuphepha uma sekukhishwe amabala, ngakho-ke ukuzivikela kuzo zonke lezi zinambuzane kulula njengokuvula isikhungo sethu se-software (noma i-Software Update app) kanye buyekeza amaphakheji azobe eselinde thina vele. Ukuze izinguquko zisebenze, uhlelo lokusebenza luzodinga ukuqalwa phansi.
