I am trying to write a non-interactive system update script.


if the following works well:

yes | dpkg --configure -a

will the following work also very well?:

yes | apt-get install --fix-broken

You have -y or --yes or --assume-yes parameters in apt-get.

Try something like

sudo apt-get install -y <package-name>


The manual page of apt-get (You can also refer to manual page with man apt-get command) mentions:

-y, --yes, --assume-yes

Automatic yes to prompts. Assume "yes" as answer to all prompts and run non-interactively. If an undesirable situation, such as changing a held package or removing an essential package, occurs then apt-get will abort. Configuration Item: APT::Get::Assume-Yes.

Contrary to this parameter, you also have


Automatic "no" to all prompts. Configuration Item: APT::Get::Assume-No.


For Vlastimil's comment, I tried

sudo apt-get install --fix-broken --assume-yes

And it works. The --fix-broken part of the command can be replaced with -f and --assume-yes with -y or --yes for convenience. This will not install any package in perticular but "can omit any packages to permit APT to deduce a likely solution", as mentioned on the manual page.
