ImportError on Calibre Server since last Debian update
Hi all,
I am running a Calibre Server on my Debian Server (Debian bullseye/sid - Linux 5.9.0-2-amd64) for a few years now, without problems. This morning, as each week, I updated my installation (apt update && apt upgrade). Since that upgrade (Through the process, Calibre was upgraded from5.4.2+dfsg-1 to 5.5.0+dfsg-1), Calibre-server fails with the following error : Code:
user@ns1:~$ calibre-server --daemonize /home/user/CalibreLibrary Traceback (most recent call last): File "/usr/bin/calibre-server", line 19, in <module> from calibre.srv.standalone import main File "/usr/lib/calibre/calibre/srv/standalone.py", line 14, in <module> from calibre.db.legacy import LibraryDatabase File "/usr/lib/calibre/calibre/db/legacy.py", line 18, in <module> from calibre.db.backend import DB, set_global_state as backend_set_global_state File "/usr/lib/calibre/calibre/db/backend.py", line 36, in <module> from calibre.utils.img import save_cover_data_to File "/usr/lib/calibre/calibre/utils/img.py", line 26, in <module> from calibre_extensions import imageops ImportError: /usr/lib/calibre/calibre/plugins/imageops.so: undefined symbol: _Py_FatalErrorFunc Is this a problem in the last Calibre upgrade... or a problem with my system? Any help welcome. Thanks a lot Salan54 |

Uninstall the debian package and install the official binaries from https://calibre-ebook.com/download_linux

Hi @kovidgoyal,
Thanks a lot for your answer. I followed your instruction and installed from the "official binaries" and it works... I suppose I will have to forget the no-less "official" Debian package and install new version from your website too. Is there a mechanism (RSS or other) to be kept updated for new versions? Thanks again, Salan54 |

calibre itself notifies you of updates, and there is an rss feed on the website as well.

Found the RSS feed and subscribed. Thanks.
As I am only using calibre-server on a headless server, I have no access to the GUI. |
