open K3b; select ISO; allow K3b to do what it needs to do (computing md5sum; click start (to begin the operation); warning message appears - pop up window Reproducible: Always Steps to Reproduce: 1.choose burn image from K3b 2.set options 3.click 'start' Actual Results: warning message - short extract follows of what appears in the message/warning window. Link given to this message above: Device 'ATAPI -iHAS524 B' Already in use by other applications (gpg-agent, 4, dbus-launch, 3014, 3, 3015, ... lsof, 6) It is highly recommended to quit those before continuing. Otherwise K3b might not be able to fully access the device. Hint: Sometimes shutting down an application does not happen instantly. In that case you might have to use the 'Check again' button. Buttons: 'Check again' 'Quit the other applications' 'Continue' Expected Results: K3b should have proceeded with the burn after clicking the start button. When you look at the thread link above where I posted about the bug please note that other users have noted seeing the same warning message as I do. Experimentation shows that by, for example, choosing 'Quit the other applications' the unwary user has closed down their Desktop and is left at a black screen. It is easy to get out of this - but the user should not have to.
Created attachment 93442 [details] Screenshot showing what K3b wants to remove I'm also having the exact same problem.
Created attachment 94174 [details] screenshot of similar dialog; k3b-2.0.80+git on plasma5 Similar screenshot; should mv this to -> confirmed This is with rpm -qa | egrep -i "k3b-2|plasma5-desktop-" k3b-2.0.80+git20150209.2250-1.5.x86_64 plasma5-desktop-5.3.91git~20150821T120904~da2274c-135.1.x86_64
Same happens here on OpenSUSE Tumbleweed with k3b-2.0.80+git20150209.2250-1.10.x86_64 (didnt upgrade recently). Should we provide some additional information?
Can't I edit a comment? However, to check if the device is in use k3b calls lsof -Fpc dev->blockDeviceName() e.g. lsof -Fpc /dev/sr0 In my case, that indeed outputs all of the processes it shows in the dialog (k3blsofwrapperdialog). The problem seems to be that lsof outputs pipes with these parameters, which you see when you omit the field selection parameter (-Fpc) : $ lsof -w /dev/sr0 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME dbus-laun 1451 gemuend 8r FIFO 0,10 0t0 23646 pipe gvfsd 1468 gemuend 6r FIFO 0,10 0t0 21185 pipe gvfsd 1468 gemuend 7w FIFO 0,10 0t0 21185 pipe at-spi-bu 1513 gemuend 4r FIFO 0,10 0t0 21214 pipe at-spi-bu 1513 gemuend 5w FIFO 0,10 0t0 21214 pipe start_kde 1577 gemuend 0r FIFO 0,10 0t0 21277 pipe start_kde 1577 gemuend 3r FIFO 0,10 0t0 21278 pipe kdeinit5 1578 gemuend 0r FIFO 0,10 0t0 21277 pipe kdeinit5 1578 gemuend 3r FIFO 0,10 0t0 22707 pipe kdeinit5 1578 gemuend 4w FIFO 0,10 0t0 21278 pipe kdeinit5 1578 gemuend 6w FIFO 0,10 0t0 22707 pipe klauncher 1579 gemuend 0r FIFO 0,10 0t0 21277 pipe klauncher 1579 gemuend 6r FIFO 0,10 0t0 22716 pipe klauncher 1579 gemuend 8w FIFO 0,10 0t0 22716 pipe klauncher 1579 gemuend 12r FIFO 0,10 0t0 21295 pipe klauncher 1579 gemuend 13w FIFO 0,10 0t0 21295 pipe kded5 1582 gemuend 0r FIFO 0,10 0t0 21277 pipe kded5 1582 gemuend 6r FIFO 0,10 0t0 22121 pipe kded5 1582 gemuend 8w FIFO 0,10 0t0 22121 pipe kded5 1582 gemuend 21w FIFO 0,10 0t0 21324 pipe kded5 1582 gemuend 22r FIFO 0,10 0t0 21325 pipe [...] Does someone know by heart how to omit pipes and sockets with lsof? Otherwise I will try to investigate tomorrow and maybe provide a patch.
[quote/]Does someone know by heart how to omit pipes and sockets with lsof?[/quote} Hi Andre, I can only speak for myself and I have to say I do not know how to do what you suggest. Thank you for keeping us udated, Hugh
I am getting quite a lot of this as well after the latest update to k3b 17.12.2, KF5 5.43, I am trying to rip my CDs to audio files. Running openSUSE tumbleweed, kernel 4.15.5. Before the update (kernel 14.4, KF5 5.40 or something) I was also getting this, but with much fewer applications, so "check again" would work. Currently check again does help much (the same applications are listed). Also, every application with a tray icon is also listed (e.g. viber).
I have the same problem, device in user http://wahoo.no-ip.org/~paka/Screenshot_20180324_161145.png

on openSUSE Tumbleweed, reverting to lsof-4.89-6.3.x86_64 solves this problem for me. lsof-4.90-1.1.x86_64 lsof-4.90-50.3.x86_64 both cause k3b to fail for me
lsof-4.91-1.1 solves this for me
