This morning, I got prompted to do a software update which I allowed to proceed.



Then my sound stopped working.



I had just recently deleted all older kernels so couldn't roll back. I used an app called "ukuu" to get back an older kernel and now my sound works.



The kernel that didn't work is linux-image-4.13.0-36-generic



The one I rolled back to that does work is linux-image-4.12.14-041214-generic



Anyone else run into this? Did I do the right thing?



ALso, this site (https://wiki.ubuntu.com/Kernel/RollingLTSEnablementStack) makes it seem that a kernel update might have happened here.



Can anyone shed any light here? I had been updating the system regularly with no problems and this is the first time encountering this issue.

This question appears to be off-topic. The users who voted to close gave this specific reason:


  • "Bug reports and problems specific to development version of Ubuntu should be reported on Launchpad so that developers can see, track and fix these issues." – user535733, karel, guntbert, Zanna, clearkimura
If this question can be reworded to fit the rules in the help center, please edit the question.












  • If the only difference is a change of kernels, then please file a bug report against the 'linux' package.

  • Not exactly sure how to do that - can you point me to somewhere to learn how to file such a bug report?

  • Oh...bug reports need to be pretty certain and exact about the problem. Developers do not have unlimited time to do basic troubleshooting, so they don't. Ubuntu participants (like you and me) are expected to learn the basic troubleshooting and proper reporting skills. to improve Open Source software like the Linux Kernel. Use the 'Search' feature to ask questions like 'how do I troubleshoot <my problem>' or 'how do I report this bug'.

  • Got it! I followed the instructions at the end of Step 3 here and it worked. I guess the Alsa drivers needed an update after the kernel update. help.ubuntu.com/community/SoundTroubleshootingProcedure

pylint3 and pip3 broken

Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I have tried sudo apt remove --purge on various packages. I get the same when I reinstall. I have also tried reinstall using aptitude. This does not work.

How to enroll fingerprints to Ubuntu 17.10 with VFS491

Image
Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I decided to switch from Windows to Ubuntu 17.10, I meet it like 8 years ago and I didn't decided to switch until now (haha). Well, my actual device is an HP Probook 4540s with a Validity fingerprint sensor (VFS491). The fingerprint sensor worked fine on Windows but I can't get it to work in Ubuntu. The device is recognized as 138a:003d but is not detected as a fingerprint scanner by some apps like Fingerprint GUI. I want to use the fingerprint scanner to log in into my user account in Ubuntu but it doesn't supports fingerprints without special software and the drivers of the fingerprint scanner are available for Windows but not for any Linux distribution. I found something on GitHub (https://github.com/eekpie/libfprint) about the integration of the VFS491 in libfprint and I think it can help but I don't know what to do with it, so that's why I need the help of the community to do it since I am...
