From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Fedora Atomic Desktop 42 switched to composefs, which has a small full partition mounted to
/
. Your "real" filesystem is mounted on/sysroot
https://fedoraproject.org/wiki/Changes/ComposefsAtomicDesktops
That makes sense, thank you! How can I clear up space in it?
You can't, it just part of how Fedora works now. Maybe Fedora should patch Dolphin to take /sysroot into account instead of /
You don't, it's the immutable root partition. You probably need to find the point it's trying to write to and link it to a location it can write to.
Note: I'm still a newbie to atomic desktops too.
You were correct, I believe I "fixed" the error with Calibre by using Flatseal to add an environment variable
CALIBRE_TEMP_DIR
that changed the Temp directory to something else.How are you trying to install Calibre? Is it via Flatpak? AppImage?
Did you try it from here? https://calibre-ebook.com/download_linux
I'm guessing that that method won't work with atomic distros. I'm guessing that it's trying to copy files to an immutable spot.
I would try looking for a Flatpak first.
I was going to suggest the portable one as a backup but that's only for Windows :(
Appreciate the response, I updated my post but I "fixed" this by changing Calibre's temp directory.
