Here's the last passing build on master, on 2nd December:
https://travis-ci.org/python-pillow/Pillow/builds/94349940

The last passing PR was on 3rd December:
https://travis-ci.org/python-pillow/Pillow/builds/94638711

The next build was today, it only changed a version number in a .rst file but errored:
https://travis-ci.org/python-pillow/Pillow/builds/95173588

This build says:

And errors like this:

$ travis_retry sudo apt-get -qq install libfreetype6-dev liblcms2-dev python-qt4 ghostscript libffi-dev libjpeg-turbo-progs cmake imagemagick
E: Unable to locate package liblcms2-dev
E: Unable to locate package python-qt4
E: Unable to locate package libjpeg-turbo-progs
The command "sudo apt-get -qq install libfreetype6-dev liblcms2-dev python-qt4 ghostscript libffi-dev libjpeg-turbo-progs cmake imagemagick" failed. Retrying, 2 of 3.

We still need sudo (for installation of packages, but it would be good to move away from that).

My own fork of this repo also errors in a similar way: https://travis-ci.org/hugovk/Pillow/builds/95189290

Do you have any suggestions how to fix this?

Thank you!

Adding sudo apt-get update before installing fixes this: https://travis-ci.org/hugovk/Pillow/builds/95190314
