Dear Yasha,

please don't run this, it will not work. It needs glibc 2.18 and this
will not work on EL7 anyway. EL7 has glibc 2.17, anything depending on a
newer version will only run containerized if at all.

There's another way to install calibre: use flatpak. Install SL's
flatpak package, then setup the repo:
# flatpak remote-add --if-not-exists flathub
https://dl.flathub.org/repo/flathub.flatpakrepo

Install the flatpak:
# flatpak install flathub com.calibre_ebook.calibre

Then as user, run it:
% flatpak run com.calibre_ebook.calibre


Regards,
Götz
