So when I tried to update I got the following message error:
W: Failed to fetch http://ppa.launchpad.net/floe/libtisch/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found
After I googled it I found this page. In "/etc/apt/sources.list" I did not find anything, like what is said in the post. BUT when I looked in the "/etc/apt/sources.list.d" folder (as it suggested) I found these two files (among other ones) that are correlated with my error.
File No 1:
name: floe-libtisch-trusty.list
in the file I found:
deb http://ppa.launchpad.net/floe/libtisch/ubuntu trusty main
# deb-src http://ppa.launchpad.net/floe/libtisch/ubuntu trusty main
# deb-src http://ppa.launchpad.net/floe/libtisch/ubuntu trusty main
File No 2: name: floe-libtisch-trusty.list.save
in the file I found:
deb http://ppa.launchpad.net/floe/libtisch/ubuntu trusty main
# deb-src http://ppa.launchpad.net/floe/libtisch/ubuntu trusty main
What I want to know is, should I delete this files? In the post is says to not delete lines that and with "main". What can I do??
