    Exclamation Cannot upgrade 18.04 to 20.04

    Hello everyone

    I want to upgrade from 18.04 to 20.04.
    Actually, I already wanted to upgrade already when 20.04 originally came out, but on the official update page it states:

    From 18.04, upgrades will not be enabled until approximately the date of the 1st 20.04 point release at the end of July.
    So I tried upgrading beginning of August the first time.
    I got all updates installed, so no problem there.

    I tried the first option offered to upgrade:

    Ensure that the package ubuntu-release-upgrader-qt is installed.

    Run in Krunner:
    pkexec do-release-upgrade -m desktop -f DistUpgradeViewKDE
    After this, exactly nothing happened. No dialog, no message, nothing at all. Waiting for up to quarter of an hour did nothing as well.
    I tried it several times, with rebooting, re-installing the package... still nothing at all.

    So I tried the second method offered:

    Alternatively if you wish to do the entire upgrade in a terminal, in Konsole do:

    sudo do-release-upgrade -m desktop
    This finally offered me a hint why nothing happened: (translated from German)

    New releases of Ubuntu are searched
    No LTS versions are avaiable.
    To upgrade to the newest non-LTS version:
    Set Prompt=normal in /etc/update-manager/release-upgrades
    So I thought, okay, they still need a bit longer for it.
    I tried several times throughout August, but still nothing.
    For the last time, I tried today, but the upgrader still says there are no LTS versions available for upgrade.

    This seems a bit fishy to me... is it still not possible to upgrade from 18.04 to 20.04?

    tokugawa-ieyasu; Hello

    The upgrade path is presently blocked - testing continues by the development team.
    Now, if you really want to upgrade now -
    sudo do-release-upgrade -d
    where 'd' is (D)evelopment - as until the block is removed 20.04 will maintain the development status. As "testing" breakage could occur.
    Insure to reset to " Prompt=lts in /etc/update-manager/release-upgrades".

    my bit to try and help
    THE current(cy) in Documentation:

    Happy ubuntu'n !

    Alternatively, you could fresh install 20.04.
