I recently installed Ubuntu 18.04 on my laptop. Then I installed Steam via the website yesterday, and it worked. When I tried to launch Steam today it simply crashed as the auto-update began. I used sudo apt-get purge steam when uninstalling and have tried to re-install both with the download from the website and with sudo apt-get install steam. The problem persists however.

This is the output I get when trying to run Steam from the terminal:

~$ steam
cp: cannot stat '/usr/lib/steam/bootstraplinux_ubuntu12_32.tar.xz': No such file or directory

  • Since the file /usr/lib/steam/bootstraplinux_ubuntu12_32.tar.xz is missing, it looks like steam-launcher is not installed. Apparently, the steam package has been replaced by steam-launcher.

    Try the following to uninstall the old package and install the new one:

    sudo aptitude purge steam steam:i386
    sudo aptitude install steam-launcher libatk-bridge2.0-0

    If steam-launcher is not available, try installing steam-installer instead.

    sudo aptitude install steam-installer libatk-bridge2.0-0
  • The package steam-launcher does not install Steam itself. Rather, it is a program that downloads and installs Steam into the user's home directory at $HOME/.local/share/Steam. If Steam is already installed, it is run.

    That Steam was interrupted during an update and is now crashing indicates a problem with the installation directory. You can force a reinstall by moving the installation folder:

    mv "$HOME/.local/share/Steam" "$HOME/.local/share/Steam.bak"
    mkdir "$HOME/.local/share/Steam"
    cp -rl "$HOME/.local/share/Steam.bak/package" "$HOME/.local/share/Steam/package"

    Then select the option to "reinstall" when running steam. A few-hundred megabytes of data may need to be downloaded.

    After successfully reinstalling and running Steam, you can look for old games in $HOME/.local/share/Steam.bak and move them to the new installation $HOME/.local/share/Steam. If you have nothing you want to move, $HOME/.local/share/Steam.bak is safe to delete.

  • Last Resort: If none of the above fixes the problem, and you don't mind reinstalling Steam from scratch, you can try deleting all Steam-related files from your home directory:

    \rm -rf $HOME/.steam*
    \rm -rf $HOME/.local/share/Steam*

  • I do not know exactly what those commands did, but now Steam works. Thanks for both your help and your patience. – PrimitiveToast May 6 '18 at 16:00
  • steam-launcher seems not to be part of the default repositories (E: Unable to locate package steam-launcher) From where do you have it? – k0pernikus May 15 '18 at 9:36
  • Steam has its own repositories. To install them, download and install the Steam deb from the Steam website. – xiota Jun 30 '18 at 8:22

run this in your terminal

  • What does that do? How is that supposed to fix the problem? – xiota Jun 30 '18 at 8:23
  • Not a solution to the original question. – Andor Kiss Feb 5 at 5:03
