Linux Mint 21.2 Mate desktop
Previously installed 7.0 on my test laptop (from 2016). Only needed
Code:
sudo apt install libxcb-cursor0
to work.
Now updated main workstation to 7.1 and the lack of libxcb-cursor0 was detected. Ran above command, up arrow twice to get to calibre install command.
Running very nicely, 6763 "books".
Thanks, Kovid Goyal!
