I have read the answers in [this post](https://askubuntu.com/questions/372810/how-to-prevent-script-not-to-stop-after-apt-get) but it doesn't seem to work for my problem.

I am executing a bash script via stdin from wget:

```
wget -O - http://serverip/subfolder/script | sudo bash

```

I've tried using `apt-get -y --force-yes install <packages..> || true`, but it still exits the script if the one of the listed is installed by apt-get.

It doesn't exit the script if all the listed packages are already installed.

The same thing happens if I have a `apt-get upgrade` and it installs package(s). It will exit the script.

I have another set of scripts, that seems to work. In that scenario, the install script is just a stub, that downloads, runs the script via `bash <scriptname>` then deletes the script. The script itself will elevate its privilege by sudoing itself. `apt-get` works as expected here.

Any insight as to how to prevent `apt-get` from terminating the script would be appreciated.
