I connected the Raspberry to my tv via HDMI cable but no sound came out, i tried to install libraries:
sudo apt-get install alsa-utils
sudo apt-get install mpg321
sudo apt-get install lame
and loaded the driver:
sudo modprobe snd_bcm2835
and executed the following command:
sudo amixer cset numid=3 2
In the instructions it says that if you are using HDMI choose "2".
When I executed the command it just says:
amixer: Control default open error: No such file or directory
First of all: What are you trying to reproduce?
Then... What does it say if you type: ?
amixer controls
Also, if you go to /boot/config.txt, what is the value of dtparam=audio ? It should be on.

I unfortunately found out during a boot that apt had failed to setup boot for an updated kernel correctly.
When I ran sudo apt dist-upgrade I found it was broken..
I have a manually installed the latest Nvidia GPUdirect/CUDA environment because of how old the official Ubuntu packages are. Obviously the install is now causing problems.
Things I tried:
I tried to find where you could "uninstall nvidia-fs". Couldn't find it on any documentation.
I tried to re-install nvidia-fs using the cuda.run installer. The didn't work successfully.
I traced out the scripts, and found a sizable script program that was called /usr/sbin/dkms, that had a "remove" flag.
ran the following command:
sudo dkms remove -m nvidia-fs -v 2.14.12
and then sudo apt dist-upgrade.
This repaired the kernel install. On to fixing the nvidia-fs install.

I'm having problems when Iḿ trying ¿to install any package or software.
My OS is Ubuntu 20.04.
I've already tried all the solutions mentioned in this post https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/1871963, including configure the UEFI, following the next comand lines:
# sudo apt-get purge grub\*
# sudo apt-get install grub-efi
# sudo apt-get autoremove
# sudo update-grub
etc.
The error message appears even when the upgrades and is installed an app from the "Ubuntu Software" application...
Errors were encountered while processing:
grub-efi-amd64-signed
E: Sub-process /usr/bin/dpkg returned an error code (1)
Thanks!
I had this same problem the last few days. Months ago I installed Ubuntu 20.04 alongside Win10 I had to switch the BIOS to AHCI from RAID as it wouldn't allow install. Then after install I could switch back to RAID to allow Win10 dual boot. However along some update it messed it up and I had to switch back to AHCI and reinstalled grub as above. It sorted the problem.

I have recently setup Ubuntu 16.10 and am trying to install PuTTY but keep getting an 'E: Unable to locate package putty' error. I have run both 'sudo apt-get update' and 'sudo apt-get upgrade'. Both complete with success. I have verified that 'main', 'universe', 'restricted', and 'multiverse' are all enabled. But I continue to get the error when trying to install PuTTY. This is the command I'm using 'sudo apt install putty'. Any thoughts on what might be going on?
I was able to finally determine that 16.10 was just too old to update properly. I have moved to 18.04 and successfully installed PuTTY.
This is a common problem when you follow the instructions on the PuTTY website.
Here is how to solve it for ubuntu:
instead of:
sudo apt-get install PuTTY
use:
sudo apt install putty
As expected the package is case sensitive but somehow even PuTTY haven't figured it out.

I've deleted yum from my server and I did wget to download yum again and extract it. In this folder, I have a lot of files:
AUTHORS completion-helper.py Makefile shell.py yumcommands.py
bin COPYING output.py test yum-cron
callback.py docs po TODO yummain.py
ChangeLog etc README utils.py yum.spec
cli.py INSTALL rpmUtils yum yum-updatesd.py
How can I install it?
Another solution to install packages is to use the RPM command. You first need to download the rpm file and then install it.
For more infos: RPM man page
So, to install yum, simply run those two commands:
wget https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-14.noarch.rpm
rpm -ivh yum-3.4.3-154.el7.centos.noarch.rpm

I installed Fabric via pip.
Got pip by:
sudo apt-get install python-pip
Got fabric by:
sudo pip install fabric
(It failed when I tried w/out sudo, and warns me about a lack of files in docs or tests).
Now I get the following:
$ which fab
/usr/local/bin/fab
$
$ fab
bash: /usr/bin/fab: No such file or directory
Huh!? I thought which searched the PATH for the resolution that would be used by bash. Am I misunderstanding something? Is Fabric, Pip, or Bash to blame here? How do I fix it?
I know for now I can run /usr/local/bin/fab or:
`which fab` deploy
But I want it to run correctly!
The following will clear where bash thinks fab is located:
hash -d fab
If which fab is in /usr/*local*/bin, but /usr/bin/fab can't be run, I would think of a broken symlink. Or /usr/local/bin/fab is a script that calls /usr/bin/fab (which doesn't exist).
Try file /usr/local/bin/fab.
