In the new GitHub Actions, I am trying to install a package in order to use it in one of the next steps.
`name: CI
on: [push, pull_request]
jobs:
translations:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v1
with:
fetch-depth: 1
- name: Install xmllint
run: apt-get install libxml2-utils
# ...
```
However this fails with
```
Run apt-get install libxml2-utils
apt-get install libxml2-utils
shell: /bin/bash -e {0}
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?
##[error]Process completed with exit code 100.
```
What's the best way to do this? Do I need to reach for Docker?

Re: Comment apt-get installer in a GitHub Actions workflow?
The [docs](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners) say:
The Linux and macOS virtual machines both run using passwordless `sudo`. When you need to execute commands or install tools that require more privileges than the current user, you can use `sudo` without needing to provide a password.
So simply doing the following should work:
```
- name: Install xmllint
run: sudo apt install -y libxml2-utils
```
