Firefox Installation Help

[rex689]

I am having trouble installing Firefox. I tried it both through the terminal and the package manager and I get a similar error.


The following NEW packages will be installed:
firefox
0 upgraded, 1 newly installed, 0 to remove and 393 not upgraded.
1 not fully installed or removed.
Need to get 0 B/24.5 MB of archives.
After this operation, 51.3 MB of additional disk space will be used.
(Reading database ... 104548 files and directories currently installed.)
Unpacking firefox (from .../firefox_20.0+build1-0ubuntu0.12.10.3_i386.deb) ...

dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

/var/cache/apt/archives/firefox_20.0+build1-0ubuntu0.12.10.3_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)


I had kubuntu before, this is my third time actually installing it, and never had this problem. Why is it having this problem?
If needed I installed it from a flash drive. I could reinstall if needed.

Thanks for any help in advance.

Hi, welcome to the forums!

Try running

sudo apt-get cleansudo rm -r /var/lib/apt/lists/*
sudo touch /var/lib/apt/lists/lock
sudo mkdir /var/lib/apt/lists/partial
sudo apt-get clean
sudo apt-get update

These will often fix such problems.

Sorry, the terminal has to be the harderst thing for me to get.

When I type in the first line, i get this error.

sudo apt-get cleansudo rm -r /var/lib/apt/lists/
E: Command line option 'r' [from -r] is not known.

I usuall use the terminal to get some programs or apt-get update option and that is it.

Thanks for the help.

Thats funny, cortman just made a typo

sudo apt-get clean

sudo rm -r /var/lib/apt/lists/*

Well, FTR- the OP made the typo- there needs to be a space between "rm" and the "-r" option.
