[PERCE-NEIGE]

Hi.

I'm a new user here, so hi everyone

I've a big problem with Calibre, using it with Linux Mint "Sonya" 64-bits.

I had no problem before trying to play a little with the Calibre-server.

I created a /etc/systemd/system/calibre-server.service.
And played a little in the terminal, with calibre commands, like start calibre-server, etc...

Doing that, I certainly didn't put the right things either in the Calibre-server etc file or in the Linux terminal, and my Calibre started to crash, so I renamed this file calibre-service.OLD

But the crashes go on. So I saved my config file .calibre -to keep my custom columns and my plugin settings- and I reinstalled Calibre, but the crashes go on. The GUI starts, and vanishes.

Calibre is the last version available in the Mint repository: Calibre 2.55.0.

How to reset it?

Thanks.
