Kugadziridzwa kweUbuntu 20.04.5 LTS kugovera kit yakaumbwa, iyo inosanganisira shanduko dzine chekuita nerutsigiro rwehardware, kugadzirisa Linux kernel uye graphics stack, kugadzirisa zvikanganiso muinstaller uye bootloader. Iko kuumbwa kunosanganisirawo zvichangobva kuitika zvemazana akati wandei mapakeji ane chekuita nekubviswa kwekusagadzikana uye nyaya dzinokanganisa kugadzikana. Zvakafanana zvigadziriso kuUbuntu 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 LTS uye Xubuntu 20.04.5tane LTS XNUMX present.

Desktop inovaka (Ubuntu Desktop) ine kernel nyowani uye magiraidhi stack nekusarudzika. Kune maseva masisitimu (Ubuntu Server) iyo kernel nyowani inowedzerwa senge sarudzo mune yekuisa. Kushandisa zvivakwa zvitsva zvinongoita zvine musoro kune kuisirwa kutsva - masisitimu akaiswa kare anogona kuwana shanduko dzese dziripo muUbuntu 20.04.5 kuburikidza neyakajairwa yekuvandudza system.
Rangarira kuti pakuunzwa kweshanduro nyowani dze kernel uye giraidhi stack, inotenderedza modhi yerutsigiro yekuvandudza inoshandiswa, maererano neiyo backported kernels uye vatyairi vanozotsigirwa chete kudzamara kuburitswa kunotevera kugadzirisa kwebazi reUbuntu LTS. Semuenzaniso, iyo Linux 5.13 kernel yakapihwa mukuburitswa iyi ichatsigirwa kusvika Ubuntu 20.04.5, iyo ichapa iyo Ubuntu 22.04 kernel. Iyo base kernel 5.4 inotumirwa pekutanga uye ichatsigirwa kune ese makore mashanu ekugadzirisa kutenderera.
Kudzosera kumashure Ubuntu Desktop kune base 5.4 kernel, mhanyisa iwo murairo:
sudo apt install --install-inokurudzira linux-generic
Kuisa kernel nyowani paUbuntu Server, mhanya:
sudo apt install --install-inokurudzira linux-generic-hwe-20.04
