The code is ok, i need to provide the absolute path to umount.
def umount(self):
'''unmounts VirtualDVD'''
#get virtualdvd folder
home = QtCore.QDir.homePath()
vpath = home + "/VirtualDVD"
cmd = 'gksudo umount ' + vpath
subprocess.Popen(str(cmd), shell=True, stdout=subprocess.PIPE)
This is strange, in terminal "gksudo umount VirtualDVD" worked fine but
not from code...
From code i have to "gksudo umount /home/user/VirtualDVD"
Thanks all for your help.
Regards,
Dim

Yes it was pasted wrong...

print proc
it fails silently.... the gksudo runs correctly. I can input the password.
But the umount does nothing. I keep have mounted the VirtualDVD folder.

I want to execute the command "gksudo umount VirtualDVD"
My code is this but it fails:
def umount(self):
'''unmounts VirtualDVD''' cmd ='gksudo umount VirtualDVD' proc =
subprocess.Popen(str(cmd),shell=True,stdout=subprocess.PIPE).stdout.read()
print proc
It looks like your code pasted incorrectly.
It pops up the gksudo dialog, and then fails. But i don't get any stdout or
stderror.
Fails how? Is there an error? Does it hang? Does nothing happen at all?
My initial thought is that you might want to try using
Popen.communicate instead of stdout.read in case you're getting
deadlocked. See the big red warning below
https://docs.python.org/3/library/subprocess.html#subprocess.Popen.stdout
Try this:
def umount(self):
'''unmounts VirtualDVD'''
cmd = ["gksudo", "umount", VirtualDVD]
^
p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE)
proc = p.communicate()
print proc
Oops!
