Problem updateing calibre on linux to 2.46.0

[ThSpeck]

Hi

When tryiung to update my calibre installation (running on centos 7) from 2.45 to 2.46, I get the following error:

[user@system ~]$ sudo -v && wget -nv -O- https://raw.githubusercontent.com/ko...x-installer.py | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"
2015-12-15 21:08:09 URL:https://raw.githubusercontent.com/ko...x-installer.py [25887/25887] -> "-" [1]
Installing to /opt/calibre
Downloading tarball signature securely...
Traceback (most recent call last):

File "<string>", line 578, in get_https_resource_securely

context.load_cert_chain(cert_file, key_file)
ssl.SSLError: [SSL] PEM lib (_ssl.c:2757)

Does anybody have a similar problem and an idea how to solve it. Is this place even the right subforum for questions like this?

Thanks in advance, Thomas

I just tied using:

sudo -v && wget -nv -O- https://raw.githubusercontent.com/kovidgoyal/calibre/master/setup/linux-installer.py | sudo python -c "import sys; main=lambda x:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main('/opt')"

Works.

Try again, it may just have been an transmission problem.

Tried again, unfortunately still the same error.

I recently aquired a ssl certificate for my machine, and the line mentioned in the error message fits to some ssl-configuration things locally. What I don't get is why something like that impacts downloading a new package or if that even is a local problem.

Nevertheless, thanks for your input.

Check your ssl certificate path, you have a mismatch somewhere.

I that calibre is downloading and checking for a system ssl cert.

calibre uses an SSL certificate bundled into the update script, and based on the posted error it successfully downloaded the installer script from github but errored in get_https_resource_securely trying to download the signature from calibre's website.


I've seen this problem before I believe sometimes distros do stupid things to their python package.

Try extracting the tarball manually, see the note about manual installs at the bottom of the download page.

Manually installed, everything worked fine. Running 2.46 now.

One other thing which may have caused this is the update from CentOS7 to 7.2 yesterday.

Anyway, I am fine now and know, what to do if something like this happens again. Thanks you all for your help.
