Can't upgrade Ubuntu 18.04 LTS -> Ubuntu 20.04 LTS

Question

Upgrade to version 20 does not complete. Goes to Read Status Information and then stops. I tried to update both through the terminal and through update-manager - the result does not change (

At first you have to install all upgrades for the bionic system by running sudo apt-get update followed by sudo apt-get dist-upgrade then run sudo do-release-upgrade -d again. — N0rbert, Aug 05 '20 at 07:23
Browse to this link: If you want to help develop and debug the latest and greatest Ubuntu and scroll down to If you want a smooth ride. I think the do-release-upgrade scripts to 20.04.1 LTS will be debugged and officially published within a few days (maybe tomorrow,Thursday). — sudodus, Aug 05 '20 at 08:49

Trying changing the update server. Use google to search all available update servers and edit the URL in the system using vim or nano.

Follow this link, it might help you..... https://linuxconfig.org/how-to-select-the-fastest-apt-mirror-on-ubuntu-linux

Edit: Sometimes Ubuntu 20.04 may be in development version in your region, if you want the stable version change your mirror server.

the update manager connects to the server successfully, the download is successful. The installation script breaks immediately after loading the data – Алексей Aug 06 '20 at 07:05

Completely uninstalled SNAP and installed it. After that, everything immediately worked correctly.
