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
