    Login incorrect for synaptic

    Hello, i just updated lubuntu 18.04 version to 20.04.1 version by pressing the upgrade upgrade button. installation was successful however since any application requires login authentication, it does not authenticate me. if instead I use the terminal, the login is successful. what problem can it have during the update phase? thank you

    The site https://lubuntu.me/focal-1-released/ has a note about upgrading from 18.04 to 20.04:-

    Note, due to the extensive changes required for the shift in desktop environments, the Lubuntu team does not support upgrading from 18.04 or below to any greater release. Doing so will result in a broken system. If you are on 18.04 or below and would like to upgrade, please do a fresh install.
    Therefore, it would be advisable to backup your personal data, download the Lubuntu 20.04 iso and do a fresh installation.

    ^ This.

    Upgrading from Lubuntu 18.04 to 20.04 is too much trouble and bound to fail (I have painful experiences myself). You need to do a fresh install, the leap from LXDE to LXQt is too large.

    DO NOT use lubuntu.net as the .ISO source, the correct download site is lubuntu.me
