[Bug 1706052] Re: cupsd crashes with SIGSEGV on ubuntu 17.04 on start

Yes, @{PROC}/*/cmdline r, and resetting to enforce fixed the printing problem. For the record, the same solution also worked for a problem I was having with the dhclient apparmor profile that was stopping NetworkManager from connecting. As for 17.10 Artful, I'm not entirely willing to do that

[Bug 1706052] Re: cupsd crashes with SIGSEGV on ubuntu 17.04 on start

Thanks, so the adding of said line to usr.sbin.cupsd helps? Can you test Artful (on a virtual machine or as a live system) to see whether it has the same problem and whether it can be fixed the same way? Note that the problems of HPLIP you mention do not have anything to do with the CUPS package

[Bug 1706052] Re: cupsd crashes with SIGSEGV on ubuntu 17.04 on start

Here's what we've got so far: Cups is back online and working in enforce mode. No errors are thrown, no crash reports. HPLIP toolbox shows the printer and the right information. I am able to print. So far, so good. However, hplip-systray is not playing along. The icon appears, but it is

Everyone with this problem, can you please add a line @{PROC}/*/cmdline r, after the line @{PROC}/*/auxv r, in your /etc/apparmor.d/usr.sbin.cupsd file, then run sudo aa-enforce /usr/sbin/cupsd and reboot. Does this solve your problem? -- You received this bug notification because you are

Another posibility is to check whether there is already a crash report file. You can attach it to this bug report. These files are in the /var/crash directory and their names contain path and name of the executable file which has crashed. In your case /usr/sbin/cupsd has crashed, so the name

Unfortunately, your gdb backtrace is touching nowhere the code of CUPS, probably due to being a sub thread which was created somewhere in the libraries. You need to get this crash registered in the Ubuntu Error Tracker. To do so, you need to follow the instructions in the crash report pop-ups. So

If you start cupsd from the command line and it reproducably crashes (or it at least crashes often enough so that you can easily get it to crash), please do the following: Run ulimit -c unlimited Then check whether there is no file named "core" in the current directory. If so, delete or rename
