sudo apt update
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys B7579F80E494ED3406A59DF9081525E2B4F1283B
sudo apt install --no-install-recommends cubic
but I got this error:
2022-05-02_11-14

then I tried to install systemd-container by command
``sudo apt install systemd-container
2

then I tried to install systemd-container by command
sudo apt install systemd=245.4-4ubuntu3.16
3

then I installed the systemd, but the OS told I've got the newest one.

If you do not have the apt-add-repository command, you can install it using:

sudo apt install software-properties-common

I am sure that I have the apt-add-repository command, but there is no option : --list
As long as I enter this command, I get this output:

Usage: apt-add-repository <sourceline>

apt-add-repository is a script for adding apt sources.list entries.
It can be used to add any repository and also provides a shorthand
syntax for adding a Launchpad PPA (Personal Package Archive)
repository.

<sourceline> - The apt repository source line to add. This is one of:
  a complete apt line in quotes,
  a repo url and areas in quotes (areas defaults to 'main')
  a PPA shortcut.
  a distro component

  Examples:
    apt-add-repository 'deb http://myserver/path/to/repo stable myrepo'
    apt-add-repository 'http://myserver/path/to/repo myrepo'
    apt-add-repository 'https://packages.medibuntu.org free non-free'
    apt-add-repository http://extras.ubuntu.com/ubuntu
    apt-add-repository ppa:user/repository
    apt-add-repository ppa:user/distro/repository
    apt-add-repository multiverse

If --remove is given the tool will remove the given sourceline from your
sources.list

apt-add-repository: error: no such option: --list

By the way, I have already installed apt-add-repository command.

OK, I had not realized that the --list option was added to apt-add-repository in a later version than what is available in Ubuntu 20.04 Focal Fossa.

Let's try this:

What is the output of...

  1. apt-cache policy systemd

  2. apt-cache policy libsystemd0

  3. apt-cache policy systemd-container

Cubic can work with any version of systemd-container >= version 237.

Package systemd-container needs the package systemd.

The issue is that, as you can see from your output, systemd-container requires systemd version 245.4-4ubuntu3.16.

However you have systemd version 245.4-4ubuntu3.17 already installed, so apt is not able to install the older version of systemd-container.

According to the Ubuntu Packages site, the highest version of systemd available in Focal Fossa is version 245.4-4ubuntu3.16.

We need to figure out from where did your Ubuntu installation get systemd version 245.4-4ubuntu3.17, and why is it not able to get the matching versions of libsystemd0 and systemd-container from the same place? Hopefully, the output of the three commands above will help answer this question.

Thanks, bro!
The output of apt-cache policy systemd is

You have version 245.4-4ubuntu3.17 of both systemd and libsystemd0.

Take a look at the details for package systemd. You can see that the official most up-to-date version should be 245.4-4ubuntu3.16.

By the way, I do not think http://mirrors.aliyun.com/ubuntu is an official mirror site for Ubuntu.

  • It is not listed here.
  • It is also not listed here.
  • It is possible this mirror is hosting the wrong versions of systemd and libsystemd0.

However, more likely is that one of your PPAs in /etc/apt/sources.list.d is supplying the incorrect versions of systemd and libsystemd0.

Take a look at which packages on your system are using systemd.

apt-cache --installed rdepends systemd

Were any of these packages installed by you (using one of the PPAs from /etc/apt/sources.list.d) ?

Also, please cut and paste the output of this command, and I'll compare your output with mine.

Thanks for your reply.
The mirror I used is listed here(the second one of your listed mirror site). It is the mirror of Alibaba in China.

And the output of apt-cache --installed rdepends systemd is:

Your package systemd matches the output I see for Focal Fossa. (Except you have a lot of i386 architecture packages, but that shouldn't matter at all).

Can you also provide the output for libsystemd0 ?

apt-cache rdepends --installed libsystemd0

There are some minor differences. (I've sorted them and removed duplicates to make comparison easy).

  • Yours is on the left.
  • Mine is on the right.

This is good news. It doesn't look like there are no other packages on your system that depend on version 245.4-4ubuntu3.17 of libsystemd0 and systemd.

Try manually installing version 245.4-4ubuntu3.16 of libsystemd0 and systemd.

sudo apt update
sudo apt install libsystemd0=245.4-4ubuntu3.16 systemd=245.4-4ubuntu3.16

Hopefully, you will be able to do this without errors from apt.

That was a pretty dangerous step you took!
I am glad you took a backup.

At this point, you have two options:

  1. Reinstall Focal Fossa or a newer Ubuntu version, and copy all your files from your backup.
  2. Recover your computer, and continue debugging this issue.

all right😂

If you recover your install from the backup, let me know, and we can try a few more things.

If you reinstall, please let me know what the installed versions of systemd and libsystemd0 are?

You might want to check these using dpkg -l systemd before and after you install any PPAs and software to see if you can identify where version 245.4-4ubuntu3.17 is coming from.

I think I might have figured out what happened that caused you to get version 245.4-4ubuntu3.17 of libsystemd0 and systemd on your system:

  1. You enabled the Focal Proposed repository from the Developer Options tab in Software & Updates.

    image

  2. You updated your system.

    You can see that version 245.4-4ubuntu3.17 comes from http://archive.ubuntu.com/ubuntu focal-proposed/main, as marked by "***" in the output below:

    $ apt-cache policy libsystemd0
libsystemd0:
  Installed: 245.4-4ubuntu3.17
  Candidate: 245.4-4ubuntu3.17
  Version table:
 *** 245.4-4ubuntu3.17 500
        500 http://archive.ubuntu.com/ubuntu focal-proposed/main amd64 Packages
        100 /var/lib/dpkg/status
     245.4-4ubuntu3.16 500
        500 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages
     245.4-4ubuntu3.15 500
        500 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages
     245.4-4ubuntu3 500
        500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages

  3. You disabled the Focal Proposed repository from the Developer Options tab in Software & Updates.

    Notice that version 245.4-4ubuntu3.17 is now listed as coming from /var/lib/dpkg/status, as marked by "***" in the output below. This output exactly matches your output for the command apt-cache policy libsystemd0 (except your mirror is mirrors.aliyun.com).

    $ apt-cache policy libsystemd0
libsystemd0:
  Installed: 245.4-4ubuntu3.17
  Candidate: 245.4-4ubuntu3.17
  Version table:
 *** 245.4-4ubuntu3.17 100
        100 /var/lib/dpkg/status
     245.4-4ubuntu3.16 500
        500 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages
     245.4-4ubuntu3.15 500
        500 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages
     245.4-4ubuntu3 500
        500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages

  4. You ended up with version 245.4-4ubuntu3.17 of libsystemd0 and systemd on your system. You also ended up with a lot of other important packages that depend on version 245.4-4ubuntu3.17 of libsystemd0.

  5. When you executed sudo apt install libsystemd0=245.4-4ubuntu3.16, this uninstalled version 245.4-4ubuntu3.17 of libsystemd0 and "bricked" your system, because all of the other dependent packages were also removed!

    You are about to do something potentially harmful.
To continue type in the phrase 'Yes, do as I say!'

You shouldn't really use the "proposed" repository, unless you are testing out unreleased software.

Nevertheless, to solve your immediate problem of not being able to install Cubic, you can continue to use the "proposed" repository to get the missing package systemd-container. To do this, you will need to temporary re-enable the "proposed" repository.

  1. Add the "focal-proposed" repository to your sources list.

    You can do this by using the Developer Options tab in Software & Updates.

    image

    Or, you can do this by adding the following line to /etc/apt/sources.list:

    deb http://archive.ubuntu.com/ubuntu/ focal-proposed restricted universe multiverse main

  2. Update your packages cache:

    sudo apt update

  3. Install version 245.4-4ubuntu3.17 of systemd-container that matches the versions of libsystemd0 and systemd on your system.

    sudo apt install systemd-container

  4. Disable the "focal-proposed" repository in your sources list.

    You can do this by using the Developer Options tab in Software & Updates.

    Or, you can comment-out or remove the corresponding line in /etc/apt/sources.list:

    # deb http://archive.ubuntu.com/ubuntu/ focal-proposed restricted universe multiverse main

  5. Refresh your packages cache:

    sudo apt update

  6. Install Cubic using the following steps:

    sudo apt-add-repository universe
sudo apt-add-repository ppa:cubic-wizard/release
sudo apt update
sudo apt install --no-install-recommends cubic

    Since Cubic works with any version of systemd-container >= 237, you should not have any issues during installation, even with the "proposed" repository disabled.

However, after installation, I can't grantee Cubic or any other software will work flawlessly on your system, since you do have packages that are currently in development and testing (libsystemd0, systemd, and many others) currently installed on your system.

Another option is to downgrade all packages you've already installed from the "proposed" repository.

If you want to try this, see How can I revert back from an upgrade to the Proposed repository?.

Of course, this is risky, so make sure you have a backup.

I suggest trying the previous solution first, because you can always try this later.

Thanks a million! Let try it now!

Bro, you're definitely right! After I enabled proposed-repository, I installed the cubic successfully! Thanks again. Thank you very very much

I’m glad it’s working for you.

This was a lot of research, and it was smart of you to keep a backup of your system.

(In the future, try not to enable the “proposed” repository unless you are helping to test packages for Ubuntu ).
