Ubuntu 18.04.5 LTS a Ubuntu 16.04.7 LTS (diskuse)

[Monika Kokešová]

Chtěla jsem upgradovat z 18.04 na 20.04, ale nešlo to. Nevíte někdo, kdy bude upgrade dostupný?

Upgrading from Ubuntu 18.04 LTS or 19.10

You can upgrade to Ubuntu 20.04 LTS from either Ubuntu 18.04 LTS or Ubuntu 19.10. Ensure that you have all updates installed for your current version of Ubuntu before you upgrade. Confirm that you also have a network connectivity to one of the official mirrors or to a locally accessible mirror as there are no offline upgrade options.

To upgrade on a desktop system:

Open the "Software & Updates" Setting in System Settings. Select the 3rd Tab called "Updates". Set the "Notify me of a new Ubuntu version" drop down menu to "For any new version" if you are using 19.10; set it to "For long-term support versions" if you are using 18.04 LTS.

Press Alt+F2 and type update-manager -c into the command box if you are using 19.10; type update-manager -c -d if you are using 18.04 LTS. Update Manager should open up and tell you that Ubuntu 20.04 LTS is now available. Click Upgrade and follow the on-screen instructions.

Zmińují late July 2020, ale asi si dávají na čas. Zatím to vypadá, že sudo do-release-upgrade nabízí max. na upgrade na poslední non-LTS(19.10). Takže na upgrade na aktuální LTS bez vynucování je asi nutno ještě čekat.

az si ten svuj problem opravis ja provadl upgrade pred par dny a slo to...

pripadne napis co konkretne znamena "neslo to"...

[PetebLazar]

Šlo upgradovat z 18.04 na 20.04 bez volby -d nebo s ní?

Já odpoledne zkusil 18.04.5 ve VB a bez -d to na 20.04 neupgradovalo, s ní ano. Možná tazatelka čeká na dobu kdy to půjde i bez něj (z pohledu tvůrců distribuce v ten správný čas na upgrade)?

[k3dAR]

jo tak, v podstate "s", resp. prehodil sem v /etc/update-manager/release-upgrades z lts na normal, coz pocitam je to same...
nezjistoval sem duvod proc neslo s lts volbou, ale protoze 20.04.1 vysla uz par dni pred tim a vydani prvniho opravneho povazuji tvurci distribuce za vhodnej cas prechodu produkcni instalace predchoziho LTS, tak sem to neresil je mozne ze maji nejake nejistoty s upgrade, ale v mem pripade Xubuntu 18.04 s hromadou PPA a "exotic" jako misto Grub pouzit Sicherboot, pro Xfce >=4.14 pouzitejch par PPA, krome EFI (a pro sichr bios_grub pro pripad Legacy pouziti) oddilu jeden LUKS, nad nim LVM... pred upgrade sem udelal snapshot vsech zavyslejch pro system lv (rootfs,var,boot,home), prvni prechod tedy nevysel kvuli 1 (z ~4300) balicku a to fs-uae-launcher z PPA, po revertu zmen z snapshotu a odinstalace tohoto balicku uz vse proslo v pohode...

[PetebLazar]

Z textu na mém první odkazu jsem to pochopil tak, že při normal to prvně provede upgrade na develop verzi(19.10) a teprve pak až na 20.04).

Upgrade to 19.10 first by changing the default behavior of the release upgrader to normal within the /etc/update-manager/release-upgrades file. When ready, execute the sudo do-release-upgrade command again. Once your system is upgraded to Ubuntu 19.10 then follow the Ubuntu 19.10 to Ubuntu 20.04 upgrade procedure while keeping the release upgrader behavior set to normal.

to platilo v tom cervnu z ktereho ten clanek je, kdy jeste nebyla vydana 20.04.1... u me sel prechod naprimo "18.04.5 => 20.04.1"...
z pocatku /var/log/dist-upgrade/main.log:

2020-08-10 02:08:30,147 INFO Using config files '['./DistUpgrade.cfg.bionic']'
[...]
2020-08-10 02:08:30,783 INFO release-upgrader version '20.04.23' started

2020-08-10 02:08:59,622 DEBUG quirks: running focalPostInitialUpdate

pripadne tohle nevrati zadnej vysledek:

grep eoan /var/log/dist-upgrade/*{.0,log}

[k3dAR]

tak sem dohledal info, duvod proc nenabidne prechod je ze jsou 2 problemy:

1. LP: #1876506 eoan to focal upgrade hangs when lvm snapshot is present
2. LP: #1891680 grub-pc upgrade support

prvni je irelevantni pro bionic->focal, kde sem lvm snapshoty mel a ok,
druhe nemuzu posoudit tim ze misto Grub mam sicherboot, ale tam uznavam ze problem kdy by spatne provedena aktualizace Grub znamenala aby uzivatel startoval Live s v chrootu preinstaloval Grub "muze" byt stopka pro povoleni upgrade...

[k3dAR]

ehm, takze upgrade jineho "stroje"(LattePanda 1.x), z 18.04.5 na 20.04.1, take sicherboot, ale nemel sem odinstalovan "grub" balicky, mel sem udelane lv snapshoty a bud c.1 se projevil i presto ze je oznacen jen pri eoan... v prubehu aktualizace se to zastavilo na:

/usr/sbin/grub-probe: error: unknown filesystem.
Found Ubuntu 18.04.5 LTS (18.04) on /dev/mapper/vg-rootfs--snap
Adding boot menu entry for EFI firmware configuration
done

pomohla (uvedene na linku):

sudo killall grub-mount

pak aktualizace pokracovala a dojela do konce ok...

btw: kdyz uz se tu "rozebira" 20.04, doporucuju (pokud stavajici nedokonalosti nejsou prekazkou) prejit pod NetworkManager/Wifi na iwd, viz vedle, rozdil v rychlosti navazani Wifi spojeni je vazne brutalni :)
