When I install Squid using sudo apt-get install squid
this message came:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package squid is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'squid' has no installation candidate
I try to upgrade after 55% it failed:
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/oneiric-backports/restricted/binary-i386/Packages 404 Not Found [IP: 91.189.91.14 80]
How can I solve this?
