On a Raspberry Pi 4, I have a newly created fully updated 64 bit Raspberry Pi OS.
I downloaded
https://download.calibre-ebook.com/b....7.1-arm64.txz
then did
sudo mkdir -p /opt/calibre
sudo rm -rf /opt/calibre/*
sudo tar xvf Downloads/calibre-6.7.1-arm64.txz -C /opt/calibre
sudo /opt/calibre/calibre_postinstall
but got the error
/opt/calibre/calibre_postinstall: /lib/aarch64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by /opt/calibre/calibre_postinstall)
I thought that Calibre v6.7 still used glibc_2.31 according to above comments.
Did I do something wrong?
