HATA: Başlangıç hatası: calibre başlatılırken bir hata oluştu. Bazı calibre işlevleri çalışmayabilir. Daha fazlasını öğrenmek için Ayrıntıları göster'e tıklayabilirsiniz.

Please install the binary calibre release from the Download page on the calibre website.

Distro packages are not supported by the calibre developer, but if you have the same problem when using the prebuilt binaries then it will get fixed.

...

Distros are known to patch calibre in unwise ways, and additionally you are now running an old version -- we are on 2.63.0 now, not 2.55.0

What is the output of

calibre-debug -c "from calibre.constants import plugins; print plugins['_regex'][0].get_properties().keys()"

Hmm, that's an error importing the regex module. I'm not familiar enough with the code of that module to be able to guess the cause of the error, you'd have to ask here: https://bitbucket.org/mrabarnett/mrab-regex

However, since the regex module is only used for some small parts of calibre functionality, I will change the next release to only import that module on demand, so most of calibre should still work.

Sorry its an old issue, but i think it may be useful for others who will found this page.

With the same installation note, i cannot use calibre in opensuse 42.2. It starts in background and says "calibre is already running". Also there is no calibre-gui.desktop file or else to start calibre -only related desktop starter files such as calibre-lrfreader.desktop, etc.

I solved the problem by starting calibre from terminal by the command:

LC_CTYPE=C calibre

I think it is about the language settings.
