ffmpeg - LarryB1607 - 07-21-2020

Was trying to install ffmpeg so Firefox could play HTNL 5. Used the command: sudo apt install ffmpeg. I was asked for my password. I could not type in the space provided. Keyboard totally worthless at that point. My distro:

Release: 18.04
Codename: bionic
Kernel 4.15.0-112-generic

What gives with the inability to type anything here?

Thanks

Hi!
From what you say, I can see you never used the command line.
When you are asked for password in the CLI, nothing is shown on the screen. You just type in the password, hit enter, then the procedure starts.
If you mistake it, you'll be asked again for the password.

If you want to get rid of the CLI, then use Synaptic Package Manager and select ffmpeg. It's easier. Wink

Good luck! Smile

I am fairly new to Linux, but I have used the terminal window to do installs and this is the 1st time this ever happened. I will see if I can find what you suggested.

Thanks

Well, I have 8 years of daily use and I still consider myself "fairly new", to quote you.
I find Linux amazing and always evolving so, there is always something for me to learn and I do my best to learn and IF I can, share the findings! Smile

I am surprised... I've noticed this behaviour on the CLI and i thought the same: "Maybe I did something wrong!". Then I searched Google for something else CLI related and I found this mention about the "frozen prompt". Then I found details in a Linux book. I forgot the name, I have lots of books on Linux and I use those on a "Need-to-know" basis. Never been a CLI geek or fan so, I use it "instead of...". Sometimes, it proves to be the most (Single?) efficient way though...

I'm sure it's there, I recently installed Linux Lite 5.0 on a "new" machine (so to speak... it's a SH but it's a great one!). See Dell Precision T1700.

Glad to help! Smile

Mark the thread as "SOLVED" if it works. Smile

Best regards and good luck! Smile

I have not upgraded to version 5 yet as I have spent a lot of time customizing what I have.

I search Lite software in Control panel and Synaptic was not there. I did a file search for Synaptic and it was not there.

I cannot use CLI to install it due to same stated reason.

If you search for Synaptic you won't find it, Linux is case sensitive and the pkg is currently called synaptic all lowercase. Open a terminal and type

Code:
apt policy synaptic

you should get something similar to this

Code:
synaptic:

Installed: (none)

Canditate: some_number_version

version table:

some_details_on_pkg

then install it by typing

Code:
sudo apt-get install synaptic

hit enter, type your passwd when asked and hit enter again, wait for synaptic to be installed, once it is, click on menu and start typing synap ... it should appear, click on it or hit enter to lauch it, once it's started you can browse categories or use the search fuction to find a pkg.

Apt offers many options to search and find pkgs which are available in its database, a very useful one is:

Code:
apt-cache

For example you could

Code:
apt-cache showpkg synaptic

which will show some details about synaptic pkg such as dependencies. Another useful apt's command is

Code:
apt show pkg_name

which as its name suggests, shows details of said pkg. The terminal is a very powerful tool and any Linux user will profit greatly by learning how to use it at this very basic level. It might look a bit challenging but once you grasps the basics you'll start to feel more comfortable at using it. Read this post for more info

Hope this helps! Smile

Adding on to [member=7109]Moltke[/member]..

Click on Menu and type in synaptic -- you should find it in Menu (or Win Key)..

Also - you mention the keyboard is unresponsive when typing,, is it just the password??
- When in the CLI and presented with a PW prompt - you will NOT see an output representation of keys entered.. No **** or P@ssw0r....
Its blank - just type the password as you normally would. Wink

Hopefully these help get you there...

[member=5414]firenice03[/member] is right, one could change that default behaviour though, for that, open a terminal and type

Code:
sudo nano /etc/sudoers

type in your password when asked, hit enter and in the sudoers file locate this line Defaults env_reset and insert this Defaults pwfeedback right under that one so it looks like this:

[Image: ksnip-20200722-165804.png]

Pay special attention to the space bettween Default and pwfeedback cause you must use it, once you've done that, hit Ctrl + o and hit enter to save your changes, then hit Ctrl + x to close nano. Now everytime you type in your password in the terminal you'll see asteriks ********** instead of a blank. Smile

Re: ffmpeg - LarryB1607 - 07-24-2020

Thanks to all, I did find the synaptic tool and just plain forgot about the password characters not acknowledged. Will do the suggestion to make them asterisks.

I hope not. Doing so will tell who ever is looking over your shoulder how many characters your password has.
