I am trying to update my system from 20.04 to 20.10

If I try through the Update Manager after installing all available updates I am toldI am up to date but that 20.10 is available. Click on Update and the Update Manager simply closes, no update.

If I try manually via Terminal it also fails. Tried the following:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

then

sudo do-release-upgrade

and it falls over telling me that I need to "Please install all available updates for your release before upgrading."

I thought they all were up to date, but it would appear from running apt-list --upgradable that libc++1 needs to be updated, but I can't find any obvious way to do that.

Any ideas?

  • Check you haven't put any holds on packages (that would prevent upgrade), eg. apt-mark showhold

  • Show the output of apt-list --upgradable . And apt-cache policy libc++1:amd64 libc++1:i386 .

try synaptic package manager (sudo apt install synaptic) and updating from there, it sometimes update packages that cannot be updated through command lines, hope this solves the problem
