[Bug 1054903] Re: update-manager says "Not enough free disk space" but there is enough space

This bug affects me also.
I'm assuming it is something related to /var/cache being mounted as a tmpfs

I haven't tried the [Unity notification "Update Manager" icon -> Install updates] trick. Do you right click on the icon to get this option? When I run...
     ~$ update-manager 
from a terminal it doesn't work even if I right click on the icon. How do I get the unity notification?

When running from the command line I get these warnings...

     ~$ update-manager 
     WARNING:root:directory '/var/cache/apt/archives' does not exists
     ERROR:root:Not enough free space: ['/var/cache']
     WARNING:root:directory '/var/cache/apt/archives' does not exists
     ERROR:root:Not enough free space: ['/var/cache']
     gpg: /tmp/tmpGDw2Px/trustdb.gpg: trustdb created

I check manually for /var/cache/apt/archives...

     ~$ ls /var/cache/apt/
     pkgcache.bin  srcpkgcache.bin

I create /var/cache/apt/archives...

     ~$ sudo mkdir /var/cache/apt/archives
     [sudo] password for jesse:
     
I run update-manager again...
     ~$ update-manager 

SUCCESS!!!

I try installing updates...

The updates work but I get the following list of error messages in the
terminal...

I'm wondering if these are just messages that would appear anyway and
are not related to this bug? Any one know? I'm assuming that they are.

As a permanent fix/workaround I added the following line to /etc/init.rc
before the "exit 0" line

<quote>
if [ /var/cache/apt/archives ]; then echo "/var/cache/apt/archives exists"; else mkdir /var/cache/apt/archives; fi || die "Command failed: mkdir /var/cache/apt/archives"
</quote>

Now need to go tell the writers of the howto's etc on SSD that
recommended putting /var/cache on tmpfs ;-)

Title:
  update-manager says "Not enough free disk space" but there is enough
  space

Status in “update-manager” package in Ubuntu:

Bug description:
  Unity notification "Update Manager" icon -> Show updates -> Install
  Updates:

      Not enough free disk space
      The upgrade needs a total of 65,7 M free space on disk '/var/cache'. Please free at least an additional 65,7 M of disk space on '/var/cache'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'.

  There is 715 M available on /var/cache :
