Thank you for your quick reply
This is the smallest VPS found with only 256MB RAM and a few GB disc space. A sandbox. And as i am a really beginner, i try not to touch to much.
So what i've
found:
calibre needs GLIBC >= 2.18 and libstdc++ >= 6.0.21
I guess this might a problem (related to your post):
Code:
[root@srv01 ~]# ls -l /usr/lib64/libstdc++.so.6
lrwxrwxrwx 1 root root 19 Apr 15 2021 /usr/lib64/libstdc++.so.6 -> libstdc++.so.6.0.19

so we're back at "updating the system" i guess
