In upgrading to Pressbooks 5.0, something appears to be amiss for me. I’ve installed the beta releases PB 5.0, Pressbooks Book 2.0, Aldine 1.0, as well as the Luther 1.8 theme. My main network page works fine, but none of the existing books are accessible (either at their URLs or from the book dashboards)–I get a HTTP ERROR 500. I’ve checked the logs and see this PHP error message: PHP Warning: Invalid argument supplied for foreach() in /var/www/wisc-dev/wordpress/wp-admin/includes/plugin.php on line 1432, referer: https://wisc-dev.pb.unizin.org/wp-admin/themes.php. I suspect that I may have done something mistakenly in my upgrade, but don’t know where to find installation instructions for Pressbooks 5.0 to check against my process.
Did you download the pressbooks-book ZIP file or install using composer?
It looks like its broken and will need to be repackaged. (Current issue: https://github.com/pressbooks/pressbooks/issues/1078 )
Please install using composer or wait until we package a new version. (might take a couple of days, sorry.)
I used the zip. What’s the composer command for this release (I’m not as skilled with composer yet)?
From within your WordPress root directory, run:
composer require pressbooks/pressbooks-book

I can not delete… I get Permission denied 
I also tried to install with composer. It works, but the pressbooks-book version 1.2 (Luther) gets installed and not 2.0.0-beta.1 (McLuhan). How can I force composer to install the beta of pressbooks-book?
This is what composer logs on the command-line during install:
php composer require pressbooks/pressbooks-book
Using version ^1.12 for pressbooks/pressbooks-book
./composer.json has been created

Writing lock file
Generating autoload files
Delete the composer.lock file. Add :version at the end like:
php composer require pressbooks/pressbooks-book:2.0.0-beta.1
Or to get the latest development branch:
php composer require pressbooks/pressbooks-book:dev-dev

I’m not sure I can help with this.
Fix your permissions? sudo ?
is not possible to install PB themes and plugins without composer?
It is possible, but Dac’s instructions were for Thomas who was trying to use Composer and having issues with the process.
because i´m having some problems updating.
I will delete all themes and I will try again.
Do I just need pressbooks-book and Aldine themes?
You need Pressbooks Book and Aldine. If you want any other themes you can install them.

Just tested this and it works properly for me.
It was some plugin compatibility, maybe. Now i´m testing in a place with as few plugins as possible (information in the end of the message):
Each time I try to create a new book, I receive that warming
I can see the cover page, but I can not to se the admin page
Also the information about how to create the title of a book is not the same. In one place we can have hyphens and in the other place we can not…

From the code comment:
To bypass this check, define PB_ROOT_THEME to the name of your custom root theme in wp-config.php.
So:
define('PB_ROOT_THEME', 'pressbooks-aldine' );`
In your wp-config should fix your existing version.
Updating to dev branch is preferable.
