I’m using Travis in building an [R package](https://github.com/TIBHannover/BacDiveR/).

Not sure why exactly, but it started to run longer than usual and abort in the `R CMD check log logs` step [with a bunch of TeX-related messages](https://travis-ci.org/TIBHannover/BacDiveR/builds/497477508#L3637-L3638), like the above or “Warning: Option `some\_TeX\_pkg’ has already been used”.

[Removing `sudo: false` from the `.travis.yml` and adding `- sudo apt-get install texinfo` below `before_install:` solved the issue](https://github.com/TIBHannover/BacDiveR/commit/72c7370f34e92bac9980490e9e7edac3efb6b18d).

[According to the Travis+R docu](https://docs.travis-ci.com/user/languages/r#apt-packages) the following might have worked as well:

```auto
apt_packages:
  - texinfo

```

or

```auto
before_install:
  - tlmgr install

```

Is there any specific benefit of either installing a TeX Live package through `apt`, or through `tlmgr`?

I have a different but similar error. In my case it’s the OSX machines that fail:

[https://travis-ci.org/ICRAR/ProFit/jobs/526741895#L965-L969](https://travis-ci.org/ICRAR/ProFit/jobs/526741895#L965-L969)

However, this seems to be a problem with the TexLive repo used by tlmgr not supporting the local TexLive installation, causing packages to be missed in the installation:
