[Kernel-packages] [Bug 1296270] Re: Have to login twice after suspending
Same issue after upgrading from Ubuntu Gnone 17.04 to Ubuntu 17.10. First I purged gnome-screensaver, but it didn't work. Then I went to Setting -> Privacy -> Screen Lock -> Automatic Screen Lock and turned it off.

[Kernel-packages] [Bug 1686107] Re: Latest kernel update gets stuck
I had a similar problem while upgrading from Ubuntu Gnome 17.04 to 17.10 on Dell XPS 15(with GTX 1050 graphics card). The kernel version that I was trying to install was 4.13.0-25. I successfully solved the problem by killing dpkg, switching to text- only console(Ctrl+Alt+F6), and running `sudo dpkg --configure -a`. It seems like this problem is related to Nvidia driver. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1686107 Title: Latest kernel update gets stuck Status in linux package in Ubuntu: Confirmed Status in linux source package in Zesty: Confirmed Bug description: I just installed the latest kernel update (4.10.0-20), but it gets stuck on the following line: Examining /etc/kernel/header_postinst.d. run-parts: executing /etc/kernel/header_postinst.d/dkms 4.10.0-20-generic /boot/vmlinuz-4.10.0-20-generic I can't finish the update process now.
