Can't install or uninstall anything in Ubuntu

uz flag
yussi

so I'm trying to install a program doesn't matter which one and then I get this error:

Processing was halted because there were too many errors.

then i searched online to find a solution so i tried the following command:

dpkg --configure -a

and that gave me the following error:

pkg: error: requested operation requires superuser privilege

so I google again and run the following command:

sudo dpkg -i vzaccess-7.5_2766f-1ubuntu1110.deb

which gave me:

dpkg: error: cannot access archive vzaccess-7.5_2766f-1ubuntu1110.deb': No such file or directory

and that's where I got stuck i'm new to linux in general and only recently installed it.

edit:

tried running sudo dpkg --configure -a and that gave me this error again. Processing was halted because there were too many errors.

and the output of sude apt update gave me this

~$ sudo apt update

It clearly says it can not find the file that you trying to run. Where on your system is this file?

Why would you try and run a command that you do not know what it does? What did you expect this program to do?

Doing `dpkg --configure -a` would be a sensible thing to do at this point, but that requires superuser privilege, so you should run that as `sudo dpkg --configure -a`.

Please edit your question with the output of `sudo apt update` and `sudo apt upgrade`. This will give us information about the state of your package management. Use [code fences](https://askubuntu.com/editing-help#code) instead of quotes, so it is formatted correctly and we can parse the information. (Three backticks on the line before and there backticks on the line after the copy/pasted output). It's OK if you don't get the editing right, just copy/paste and we can correct the formatting via moderation tools.

Can you tell us what software you are trying to install? Since you are new to Linux, try to stick with software that's in Ubuntu's repositories. Installing packages from PPA or from `.deb` files that you download off the internet can sometimes break your system, especially if the software is not well-maintained. Installing software without using apt or dpkg can also be complicated. If you do have to use software outside of Ubuntu repos and you have to follow some guide, research about each command so that you do not blindly run commands in terminal. This will also help you learn the OS.

Why did you add the "nathan-renniewaldock/flux" ppa to your system? Where did you read about doing that? Please edit your question and clearly explain what you are trying to do in the first place, when you started encountering these issues. The obvious problem you are having is that the ppa does not support `focal`.

So is your actual, original problem that `redshift` isn't working?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
