Can't update plugins
Hi there,
I'm having 2 issues with plugins; here is the 1st one: When trying to get additional plugins (Preferences > Get plugins to enhance Calibre), I get the following error message: calibre, version 3.32.0 ERROR: Update Check Failed: Unable to reach the plugin index page. Traceback (most recent call last): File "site-packages\calibre\gui2\dialogs\plugin_updater.py", line 441, in __init__ File "site-packages\calibre\gui2\dialogs\plugin_updater.py", line 65, in read_available_plugins File "site-packages\calibre\utils\https.py", line 202, in get_https_resource_securely File "httplib.py", line 1278, in connect File "ssl.py", line 353, in wrap_socket File "ssl.py", line 601, in __init__ File "ssl.py", line 830, in do_handshake SSLEOFError: EOF occurred in violation of protocol (_ssl.c:590) This happens when connecting through the proxy. It all goes fine with a direct internet connection The (not so) funny thing is that downloading metadata & covers works OK through the proxy and with a direct connection Any help would me very welcome!

updating plugins uses private https certificates, your proxy presumably unwraps https traffic so cannot handle that.
Download the plugin zip files manually using a browser and install them directly. |

Bypassing the proxy would indeed be a workaround, but I cannot consider this as a solution The reason is that downloading metadata & covers goes successfully over https The question becomes then: why is one https connection handled properly while the other one fails ? |

I already told you why, because it uses private https certificate, which prevent your proxy from interfering with the https traffic like it does with https traffic that uses public certificates.

Plugins are NOT hosted on Kovids servers. The server supplies the certificate. Public Certificates co$t If you wish to maintain your network configuration, do as Kovid suggests: Go to the Plugins Section of this forum and use the Index (a sticky) to locate the specific PI thread: then download the Current PI (usually in post #1 ); open Preference: Miscellaneous: Plugins: use the appropriat buttons near the bottom to Remove / Add a PI from file |

I can live with about anything if I understand the reasons why Actually, as bypassing the proxy is just 2 clicks and a password away, and I know how to do this, I will keep using this workaround If I start messing around with prefs, downloads, adding and removing stuff, knowing me, I'm pretty sure I will end up screwing my PC... Thanks again! |
