Brisk menu crash, software repository issues, unmet dependencies

I own this one.

Signal advised me that it was time to update, opened a terminal and copied and pasted in the 3 lines of instruction and nothing seemed to happen. Panicked, closed down and tried again.

I am now getting major error messages and functionality issues including:

  • Cannot open Software boutique it simply shows it's opening and then closes

  • Notification gives me an error message upon boot - see attached. Installed packages have unmet dependencies. I am also getting regularly the Sorry Ubuntu error message and have attached screenshots of the output.

  • Terminal giving me the following error message when I try various repairs.
    E: Type 'sudo' is not known on line 2 in source list /etc/apt/sources.list.d/signal-xenial.list
    E: The list of sources could not be read.
    E: Type 'sudo' is not known on line 2 in source list /etc/apt/sources.list.d/signal-xenial.list
    E: The list of sources could not be read.

Not really looking forward to doing a fresh install unless I absolutely have to so hoping this wonderful community can assist this newbie.

Thanks in advance as usual.

Please show the contents of this file with cat /etc/apt/sources.list.d/signal-xenial.list - add it to the reply. How did you add it to the system?

Hoping this is what you are looking for. I have provided the command line from the signal website that I used. As stated, it did not seem to be working so attempted to add it twice.

curl -s https://updates.signal.org/desktop/apt/keys.asc | sudo apt-key add -
echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" | sudo tee -a /etc/apt/sources.list.d/signal-xenial.list
sudo apt update && sudo apt install signal-desktop

ti[email protected]:~$ cat /etc/apt/sources.list.d/signal-xenial.list -

deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main # disabled on upgrade to eoan

sudo apt update && sudo apt install signal-desktop

deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main

deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main

deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main

deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main

deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main

You have to execute the main command again:

echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" | sudo tee /etc/apt/sources.list.d/signal-xenial.list

It will end with filling the /etc/apt/sources.list.d/signal-xenial.list file with single line:

deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main

And then you need to update package lists and install the Signal package:

sudo apt update
sudo apt install signal-desktop

Wow...that was a quick reply and MUCH appreciated.

Will try that later today as I am currently away from that computer.

Will keep you posted. Thanks Norbert_X!

Finally able to get to the computer.

Entered in the "echo" command, asked for my password. Entered password successfully.

Copied and pasted your "deb" command and received this error message:

Command 'deb' not found, did you mean:

  • command 'den' from snap den (1.2.0-0)*
  • command 'dub' from snap dub (1.18.0)*
  • command 'derb' from deb icu-devtools (63.2-2)*
  • command 'debi' from deb devscripts (2.19.6ubuntu1)*
  • command 'dab' from deb bsdgames (2.17-28)*
  • command 'debc' from deb devscripts (2.19.6ubuntu1)*
  • command 'dex' from deb dex (0.8.0-2)*
  • command 'deb3' from deb quilt (0.65-3)*
  • command 'edb' from deb edb-debugger (1.0.0-1build2)*
  • command 'dep' from deb go-dep (0.5.4-2)*
  • command 'dub' from deb dub (1.16.0-1build1)*
  • command 'xdeb' from deb xdeb (0.6.7)*

See 'snap info ' for additional versions.

Did not move further in the process. Can you advise next steps please?

Thanks in advance...again.

You should not execute second code-block (deb ...).

You have to execute only first colored block:

echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" | sudo tee /etc/apt/sources.list.d/signal-xenial.list

Ahhhh....the learning path is sometimes so simple but I made it complex.

Followed your instructions, all up to speed now!!! Thank you!
