Thorium on some Linux distributions: AppArmor SUID ElectronBuilder (`sudo chmod 4755 /opt/Thorium/chrome-sandbox`)

[llemeurfr]

From a user:
Linux versions of thorium reader 3.0.0 and 3.0.1 alpha (amd64, either deb and AppImage) do not work here on Linux Mint 22. Freezes after importing ebooks, no reaction after opening the books.

My Linux distribution is Linux Mint 21.3 Virginia (which is based on Ubuntu 22.04 jammy) as shown by lsb_release -a

ldd --version
===>
ldd (Ubuntu GLIBC 2.35-0ubuntu3.8) 2.35

ldd `which ls` | grep libc

libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6

===> GNU C Library (Ubuntu GLIBC 2.35-0ubuntu3.8) stable release version 2.35.

The AppImage runs fine, the library window behaves as normal, but the reader window is completely broken: several seconds wait between each interaction with the GUI or the publication content. Sometimes the React UI does not display at all (the pub info dialog, for example)

Same story when installing the Debian package.

The CPU spikes hard for several seconds when interacting (mouse clicking) in the reader window.

I am using Thorium 3.0.0 AppImage on OpenSUSE Tumbleweed and Gnome 46.

Since starting to use this version I have noticed that loading an epub file is taking a very long time. I have tried several files that worked well on previous versions so can discount the files themselves.

Great new look by the way!

Thanks
Paul

Not working as well for Ubuntu 24.04.1 LTS.

$ ./Thorium-3.0.0.AppImage

Thorium-3.1.0-alpha.1.11177520504.AppImage also does not work on Ubuntu 22.04 LTS variants (Pop!_OS).

Basically the books (e.g. PDF & EPUB in my case) can be loaded but once opened for actual reading, it is difficult
to move from page to page or even within the page. Navigation through the pages is very sluggish.

Needs to use a more recent fuse also. Needs fuse2, distro have moved to 3.

Hello, Thorium is packaged automatically by Electron Builder to distribute on Windows, Linux, Mac OS. I expect that as we update the build process software dependencies, Thorium will automatically benefit from the latest and greatest tech available.

At the risk of only adding a "me too" to this issue, ... me too. ☹️ Same as @kianmeng :

It would be good to have Thorium working "out of the box" on current Ubuntu.

Epubs are also super-slow for me. More than 10 second for any action. For Thorium 3.0 and 3.1.
