I tried to install KVM on ubuntu 17.10 and got this error:

**anuragabhi@abhishek-Notebook:~$** sudo aptitude install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils

To solve DPKG error, I tried the solution given in the link:

E: Sub-process /usr/bin/dpkg returned an error code (1) [related to google chrome]

But nothing seems to work.

I tried some commands, and the output is as follows:

anuragabhi@abhishek-Notebook:~$ cat /usr/sbin/update-info-dir

The first error message tells the tale: /usr/sbin/update-info-dir: 3: /etc/environment: $: not found. As you can see, the update-info-dir script only uses /etc/environment as a parameter to . it (. is also the bash command source), to set some parameters in the environment of the current process.

On my Ubuntu 16.04.4 system (YMMV), it contains the initial setting of PATH, a Very Important Variable. PATH is the colon-separated list of directories along which bash searches for executables.

You can fix your problem:

/usr/bin/sudo /bin/rm /etc/environment
echo 'PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games" | /usr/bin/sudo /usr/bin/tee /etc/environment'
/bin/chmod 0644 /etc/environment
