Thank you Wes Newell for your reply. I only installed ubuntu on this computer (big big big mistake) I do not have the grub menu at start.
After typing many commands which I did not understand ubuntu started. I have lost the sound however and now I am afraid to turn it off. If I run: dpkg -l | grep linux-imagerc linux-image-4.15.0-20-generic 4.15.0-20.21 amd64 Signed kernel image generic rc linux-image-4.15.0-22-generic 4.15.0-22.24 amd64 Signed kernel image generic ii linux-image-4.15.0-23-generic 4.15.0-23.25 amd64 Signed kernel image generic ii linux-image-4.15.0-24-generic 4.15.0-24.26 amd64 Signed kernel image generic ii linux-image-generic 4.15.0.23.25 amd64 Generic Linux kernel image And currently: uname -r: 4.15.0-24-generic Which commands should I run to purge that kernel and run the previous one? Should I do it from tty? or from the current session? Should I wait for an update or will that make it worse... -- 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/1779827 Title: failure to boot with linux-image-4.15.0-24-generic Status in Ubuntu: Confirmed Status in linux package in Ubuntu: In Progress Status in The Bionic Beaver: Confirmed Status in linux source package in Bionic: Fix Committed Bug description: This was the last OK then my 18.04 hangs after an update this morning. 07:00 AM CEST Last Ok in boot was Started gnome display manager. dispatcher service ...... tem changes.pp link was shut down Tried install lightdm from command line and the response was lastest already installed.
