F41 Calibre installation script fail with openssl error

Ask Fedora
1

Hi, i’m trying to install the latest version of Calibre (ebook management software) using their script (i’m on Asahi Linux, Fedora 41)

sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin

but i have this error:

...
  File "/usr/lib64/python3.13/ssl.py", line 1372, in do_handshake
    self._sslobj.do_handshake()
    ~~~~~~~~~~~~~~~~~~~~~~~~~^^
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: Basic Constraints of CA cert not marked critical (_ssl.c:1020)
...

I don’t know if it’s an error due to my system or a general problem of Fedora 41 openssl python packages.

Thank you

Most likely it’s a bug in the script you are running that is accessing a web site that has an invalid certificate.

Thanks for your response!

Calibre is packaged in Fedora, you should be able to install it with dnf install calibre.
