Hello, I hit a strange emacs issue, which appeared after upgrading to bullseye (I think):
I have a virtualbox filesystem mounted using the standard virtualbox mechanisms: rd@Testing:~$ mount |grep dor1rt dor1rt on /mnt/dor1rt type vboxsf (rw,nodev,relatime) rd@Testing:~$ rd@Testing:~$ ls -l /mnt/dor1rt/Local/Managed/sb.blog -rwxrwxrwx 1 root root 47086 Apr 19 13:40 /mnt/dor1rt/Local/Managed/sb.blog rd@Testing:~$ While e.g. the standard KDE editor has no problems opening, editing, and saving the file, emacs opens the file in read-only mode. I can disable read-only mode, but emacs refuses to write, I get "Unlocking file: Operation not permitted." Even worse, even if I try to save to ~/ I get the same unlocking error. Here is what I get in the *Messages* buffer: Loading /etc/emacs/site-start.d/00debian.el (source)...done Loading /etc/emacs/site-start.d/50asymptote.el (source)...done Loading /etc/emacs/site-start.d/50autoconf.el (source)...done Loading /etc/emacs/site-start.d/50cmake-data.el (source)...done Loading /etc/emacs/site-start.d/50dictionaries-common.el (source)...
