Package: vlock
Version: 2.0-1
Severity: important
Hello,
it seems that even if the user is in the vlock group (as suggested in
NEWS.Debian and in upstream SECURITY), options -s and -n don't work:
=====
[EMAIL PROTECTED]:~$ groups
luca adm disk dialout cdrom floppy audio src video plugdev staff fuse vlock
[EMAIL PROTECTED]:~$ vlock -a -s
vlock-nosysrq: could not open '/proc/sys/kernel/sysrq': Permission denied
[EMAIL PROTECTED]:~$ vlock -n
vlock-new: cannot open virtual console: Permission denied
[EMAIL PROTECTED]:~$
=====
The problem is that vlock.postinst is not setting the correct
group/mode during upgrades. This cause also the failure of package
de-installation (thus severity important):
=====

=====
Manually setting group/mode/overrides as in vlock.postinst solved the
issue.
BTW, since vlock.postinst calls dpkg-statoverride with the --update
option, you don't need to manually set the group/mode,
dpkg-statoverride will do it.
Thx, bye,
Gismo / Luca
