[Bug 156070] Re: "Failed Upgrade tool signature" when using do-release-upgrade

I am having this issue when using apt-cacher-ng and trying to do-release
upgrade from Hardy 8.04.2 to Intrepid. This is the relevant output:

magicfab at andrea:~$ sudo do-release-upgrade
Checking for a new ubuntu release
Failed Upgrade tool signature
Done Upgrade tool
Done downloading            
extracting 'intrepid.tar.gz'
authenticate 'intrepid.tar.gz' against 'intrepid.tar.gz.gpg' 
exception from gpg: GnuPG exited non-zero, with code 131072
Debug information: 

gpg: WARNING: unsafe permissions on homedir `/tmp/tmp-AFwaU'

gpg: can't open `/tmp/tmp-AFwaU/intrepid.tar.gz.gpg'
gpg: verify signatures failed: file open error

Authentication failed
Authenticating the upgrade failed. There may be a problem with the network or with the server. 
magicfab at andrea:~$ 

I can do the upgrade by disabling the cacher, but that defeats the
cacher purpose!

The fix for this should be backported.

** Changed in: apt-cacher-ng (Ubuntu Hardy)
       Status: New => Confirmed
