This thing again

A few days ago I decided to try to bust out of the Amazon well for ebooks. After some reading I discovered that Kobo allows you to have a portion of your purchase go to local bookstores. I bought a cheap title as a trial and it worked OK. I've also been wanting to upgrade my reader, my 2015 Paperwhite is still working fine but the new ones are waterproof, have very nice light temperature control, etc. I looked and decided on a Kobo Clara 2E and got that in yesterday.
Then when I went to try to sync it, I couldn't get Calibre (under Linux) to recognize it at all. It mounted, I could see the storage, but no bananas on Calibre. I could copy epubs in manually and they worked. I plugged it into a Windows laptop and it came up in Calibre.
So anyway I swapped my Windows SSD back in again. For the most part it doesn't much matter if I'm under Windows 11 or Linux Mint, I hardly notice the difference. For scanning and label printing I had a Win10 VM but I only do those things once a month-ish so no big deal, but managing my ebooks is very frequent and syncing my reader is at least a weekly task and too much bother to try managing all that under a VM.

Anyway, today is travel to Windycon so that's fun.
