[Bug 879107] [NEW] apt-get re-encodes URL-encoded characters from an HTTP redirect

[Matt Alexander]

Public bug reported:

Using apt-get on Ubuntu 10.04, for example, installs of packages that
contain a '+' character in the name when being redirected to another
host fail to install.  If the server encodes '+' as %2B, then apt-get
will re-encode the '%' as %25, resulting in %252B in the new GET URL.
This breaks installs.

This appears to have been fixed in Debian upstream apt-0.8.15, but it's
still a problem for the LTS releases.  http://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=602412

Please backport the fix in apt-0.8.15 to Ubuntu 10.04.  This is
important for enterprises running Ubuntu 10.04 that use a mirror for
package installs.
