• Mune shiftfs, chaiyo FS yekumapa mushandisi namespace makomo mapoinzi akagamuchira rutsigiro rweiyo yakananga I / O (O_DIRECT, shanda pasina kubhidha uye kupfuudza cache).
• Iyo ubuntu-web-launchers package yakabviswa kubva pakurongwa rwezvakakurudzirwa kunyorera;
• MuThunderbird, yekuchinjana mafaera muFilesLink modhi, uko chinosungirirwa chinochengetwa kumasevhisi ekunze aine chete zvinongedzo zviri kuendeswa kunze kwekuchengetedza sechikamu chemeseji, sevhisi yeWeTransfer inoshandiswa nekutadza.

Kuendeswa kweshanduro idzi nyowani kernel uye giraidhi stack, inoshandiswa mune inoenderera yekuvandudza modhi yekutsigira zvinoenderana nezvakadaro, iyo inotakurika tsanga uye madhiraivha zvinotsigirwa chete kusvikira iko kunotevera kugadzirisa kugadzirisa kweiyo Ubuntu 18.04 LTS bazi.

Semuenzaniso, iyo yakarongwa Linux 5.3 kernel mune yazvino vhezheni ichaenderana kusvika kuUbuntu 18.04.5 vhezheni (iyo ichapa iyo Ubuntu 20.04 kernel). Nepo iyo huru Ubuntu 18.04 LTS kernel (4.15) yakaunzwa pakutanga ichizotsigirwa panguva yese yekuchengetedza.

Tsigiro yeiyo LTS vhezheni yeUbuntu 18.04 ichagara kusvika Kubvumbi 2023, mushure mezvo imwezve 5-gore yekuvandudza ichagadzirwa sechikamu cheyakasiyana yakabhadharwa rutsigiro (ESM, Yakawedzerwa Kuchengetedzwa Kwekuchengetedza).

Kune avo vanofarira kugona kuwana izvo zvitsva zveiyi vhezheni nyowani, vanogona kuendesa avo aripo maficha kune iwo mavhezheni matsva eiyo kernel uye girafu girafu, nekuita unotevera kuraira:
