Hello,
This forum doesn’t let me post pictures but I had posted this question here Recovery error after reboot (View topic) • Apache OpenOffice Community Forum. The solution given there didn’t work. Can someone here help?
Did you delete the “.~lock” files in ~/.config/libreoffice/4/user/backup? Since they’re hidden, you might not actually have deleted them.
~/.config/libreoffice/4/user/backup
rm .~lock.*
(I had the exact same problem, and deleting them is what solved the problem.)
