Update Calibre on ChromeOS

Patricia1066 · 05-28-2022, 09:25 AM

I run ChromeOS 103 beta, no Developer access needed, and have figured out how to update Calibre so thought I would share.

I run linux (Debian Bullseye) within the ChromeOS container, and when Calibre requires sudo permission as root no password was set so you cannot go further.

The first time you run root@penguin in crosh you can set a password. If you want to run a script in Terminal requiring sudo permission within the container this is the password that is required.

Close Terminal and Calibre

Open crosh (Ctrl + Alt + t)

vsh termina (to open root)
lxc start penguin
lxc exec penguin -- bash (opens root@penguin)
passwd (enter new password twice)

sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin

exit

The calibre install froze today and I could not reopen. I deleted the linux container, saving my books to the chromeOS/Downloads folder. The install failed, ImportError: cannot import name 'QWebEngineUrlScheme' from 'qt.webengine'

The error is the same as bug 1955911, and installing libnss3 allowed me to install without errors.

With the latest version of Calibre (6.0), I got a new error message, and had to do a `sudo apt-get install libopengl-dev`. Then it worked like a charm.

Thanks popup-ch that made the difference, allowed me to upgrade to 6.1
