Canonical yakafumurwa Mazuva mashoma apfuura kuburitswa kwekuvandudzwa akasiyana LTS vhezheni yayo yekushandisa system "Ubuntu" uye mune iyi iri mamiriro eiyo yekutanga vhezheni yekuvandudza ye Ubuntu 20.04.1 LTS, nepo vhezheni yacho 18.04 ndiko kubvisa kuvandudzwa kwakagamuchirwa uye ye16.04 yechinomwe.
Muchiitiko cheyaviri yekupedzisira, akasiyana meseji anoratidzwa yemapakeji anoumba iyo system, pamwe neiyo kusanganisirwa kweshanduro nyowani dzeLinux kernel, grafiki stack uye zvimwepanguva yeiyo vhezheni 16.04 chete zvigadziriso zvebugs zvinosanganiswa uye mhinduro kumatambudziko akarongwa seakakomba.
Ubuntu 20.04.1
Iyo nyowani nyowani inosanganisira zvinyorwa kune mazana emazana mapakeji kugadzirisa kusagadzikana uye kugadzikana nyaya. Iyo nyowani vhezheni zvakare inogadzirisa mabugs mune iyo inosimudza uye bootloader.
Kuburitswa kweUbuntu 20.04.1 kwakaratidza kudzikisira kwekutanga kwekuburitswa kweLTS.
Shanduko dzinonyanya kukosha dzinosanganisira:
- Performance optimizations yakaitwa. AES-GCM Hardware yekumhanyisa rutsigiro yakagadziridzwa kuita zfs-linux.
- Iyo GNOME Kudzora Center ine yakagadzirwazve zvigunwe zvigadziriso dialog.
- Wakawedzera VPN Wireguard rutsigiro.
- Iyo Linux kernel yekutengesa kweOEM yakagadziridzwa kuita 5.6 (Ubuntu 20.04 ngarava ine 5.4).
- Wakawedzera rutsigiro rwekutamisa iyo LED kune nyowani HP notibhuku.
- Wakawedzera rutsigiro rweNVIDIA's proprietary driver server nhevedzano.
- Iyo yekumisikidza inosanganisira kutsigira kweZFS autotrim. Rarama-kuvaka inowedzera riscv64 rutsigiro.
- Dzakagadziridzwa shanduro dze libreoffice (6.4.4), GNOME (3.36.2), snapd, evince, golang-1.14, curtin, nautilus, gedit, gnome-control-center, shanduko-data-server, mutter, gnome-software mapakeji , shotwell, netango.io, OpenStack Ussuri, cloud-init, open-vm-tools, gtk + 3.0, ceph, sosreport, libgphoto2.
- Kubatanidzwa kweiyo kernel nyowani, madhiraivha, uye magiraidhi emagetsi anotarisirwa muna Kukadzi 20.04.2 kuburitswa, sezvo zvinhu izvi zvichizotumirwa kubva kuUbuntu 20.10 kuburitswa, uko kusingawanikwe kusvika kudonha uye kunozoda imwe nguva yekuyedza. .
Ubuntu 18.04.5 LTS
Kune iyi vhezheni, uku ndiko kugadzirisa kwekupedzisira kunosanganisira shanduko yekuvandudza rutsigiro rwehardware, kugadzirisa Linux kernel uye grafiki stack uye gadzirisa yekumisikidza uye bootloader zvikanganiso.
Sezvo mune ramangwana, zvigadziriso zvebazi 18.04 zvichaganhurirwa pakubvisa kusagadzikana uye matambudziko anokanganisa kugadzikana. Panguva imwecheteyo, zvakagadziriswa zvakafanana zvinounzwa Kubuntu 18.04.5 LTS, Ubuntu Budgie 18.04.5 LTS, Ubuntu MATE 18.04.5 LTS, Lubuntu 18.04.5 LTS, Ubuntu Kylin 18.04.5 LTS, uye Xubuntu 18.04.5 LTS.
Iyo nyowani vhezheni inopa mapakeji ekuvandudza ne kernel 5.4 (Ubuntu 18.04 yakashandisa kernel 4.15 uye Ubuntu 18.04.4 yakashandisa kernel 5.3).
Graphics stack zvikamu zvakagadziridzwa, kusanganisira zvinyorwa zvitsva zve Mesa 20.0, X.Org Server inotakurirwa kubva kuUbuntu 20.04 uye madhiraivha evhidhiyo eIntel, AMD uye NVIDIA machipisi.
Wakawedzera rutsigiro rweRaspberry Pi 4 bhodhi akasiyana ne8GB RAM. Yakagadziridzwa vhezheni dze snapd, curtin, ceph, cloud-init mapakeji.
Kubudiswa kweUbuntu 18.04.5 kunotengeswa sekushandurwa kwekushandurwa uye kunosanganisira zvinhu zvekusimudzira kuUbuntu 20.04.1.
Zvine musoro kushandisa iyo nyowani vhezheni yakapihwa chete yekuisa nyowani, asi kune matsva masystem kuburitswa kweUbuntu 20.04.1 LTS kwakanyanya kukosha, iyo yatopfuura danho rekutanga rekudzikamisa mushure mekutanga kwebazi idzva reLTS.
Sisitimu dzakamboiswa dzinogona kugamuchira shanduko dzese dziripo muUbuntu 18.04.5 kuburikidza neyakajairwa yekumisikidza yekuisa system.
Tsigiro yekuburitswa kwemagadziriso uye ekuchengetedza maficha eiyo server uye desktop editions ye Ubuntu 18.04 LTS ichagara kusvika Kubvumbi 2023, mushure meizvozvo zvigadziriso zvichaumbwa mune yakasarudzika yakabhadharwa rutsigiro (ESM, yakawedzerwa kuchengetedzwa kwekuchengetedza) kweimwe makore mashanu.
Ubuntu 16.04.7 LTS
Pakupedzisira kubazi iri, inogadziridza iyo inosanganisira chete iyo yekuwedzera mapakeji meseji ane chekuita nekutadza kubviswa uye matambudziko anokanganisa kugadzikana.
Chinangwa chikuru cheshanduro nyowani ndeyekugadzirisa iyo yekuisa mifananidzo. Sezvakaita mushanduro yapfuura, Linux kernels 4.15 uye 4.4 zvinopihwa, pamwe neMesa, X.Org Server inotakurirwa kubva kuUbuntu 18.04 uye madhiraivha evhidhiyo eIntel, AMD uye NVIDIA machipisi.
Tsigiro yekuburitswa kwemagadziriso uye ekuchengetedza maficha edesktop uye server editions e Ubuntu 16.04 LTS ichagara kusvika Kubvumbi 2021.
16.04 inoita kunge isina maturo kwandiri, nekuti ichakurumidza kuve isina rutsigiro ..
Izvo zvinofanirwa kutariswa kuti kune zvikoro, mahofisi, makambani (ma) izvo zve x kana chikonzero hazvigone kugadzirisa kana kutamira kune imwe vhezheni (taura mutengo, kufamba kwedata, nezvimwewo) uye tora mukana weichi chimiro cheUbuntu kuti udzivise kutama. makore maviri ese.
