I did not perform any operations, and no operations were pending.
There are 3 drives: sda sdb sdc
Selecting File->quit

Failed to execute operation: Access denied
Can anyone shed some light on this?
selinux?
Does strace shed any light on what it was doing just before the error?

Hmm. It looks like this message comes from a subcommand that gparted invokes,
or a subprocess before executing the subcommand.
See here:
access("/bin/systemctl", R_OK) = 0
rt_sigprocmask(SIG_BLOCK, [INT CHLD], [], 8) = 0
rt_sigprocmask(SIG_BLOCK, [CHLD], [INT CHLD], 8) = 0
rt_sigprocmask(SIG_SETMASK, [INT CHLD], NULL, 8) = 0
clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7ff209b239d0) = 12884
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGINT, {0x559e190c9290, [], SA_RESTORER, 0x7ff209192a50}, {SIG_DFL, [], SA_RESTORER, 0x7ff209192a50}, 8) = 0
wait4(-1, Failed to execute operation: Access denied
[{WIFEXITED(s) && WEXITSTATUS(s) == 1}], 0, NULL) = 12884
That "Failed to execute operation: Access denied" is not an error from a system
call in the main process; instead if is embedded in the stderr output. The
sequence above suggests that gparted is about to invoke the systemctl command,
and perhaps that issues the error, or gparted issues the error in the cloned
subprocess.
Please rerun strace with the "-f" option to follow forked processes. That
should reveal more detail.
