Public bug reported:
Binary package hint: update-manager
In 32 Bit Karmic Koala (9.10), running off a 4G usb stick, when
mounting a 256M ramdisk for /tmp from fstab, update-manager claims
not enough space is available on /tmp. The /tmp ramdisk works fine,
able to hold a 70M zip and unpack it, and there is lots of space
left on /. Note that a 64 bit Karmic on a 4G stick with an
identical ramdisk, update-manager works fine. However, even on the
64 bit version, df shows 0 avail for /tmp.
Update-manager can download the package information, but fails to
download any actual packages. The first time update-manager was run,
11 packages of 5.2M found, soon after, 12 packages of 5.3 meg were
found. Not sure if the 5.234k changed when 12 packages found. No
later changes of the 5.234 were seen, regardless of the size of the
download (larger or smaller).
Example:
Update Manager finds 12 packages needing 5.3m, but selecting the
Install button leads to a popup error window:
Not Enough Free Disk Space
The upgrade needs a total of 5,243k free space on disk '/tmp'. Please free at
least an additional 5,243k of disk space on '/tmp'. Empty your trash and
remove temporary packages of former installations using 'sudo apt-get clean'.
Removal of the /tmp line in /etc/fstab, reboot, and update-manager
works fine. Restore the /tmp line in fstab, (wait a bit) and next
time two packages sized 1.2M are avail, the original error window
complaining of needing 5.234k reappears. Even later, when the
packages to download total 39.9M, the message remains the same --
5,234k needed. This bug may be related to 285096. Firefox has no
trouble downloading files. Cannot find any other program having
problems, even the Synaptic Package Manager works fine.
"df -a" output is all zeros for /tmp, even on the 64 bit system
which seems to have no problems with update-manager.
The below system info is from the time when update-manager
finds 12 packages.
System info:
Presario V3000
AMD Turion 64, 2G mem, an ext2 filesystem on a 4G usb stick for
root, no swap, no proprietary drivers in use. Karmic 9.10, both
32 and 64 bit versions, patched to date 12/8/2009.
The line in /etc/fstab creating the /tmp ramdisk:
$ fgrep ramfs /etc/fstab
ramfs /tmp ramfs size=256M,mode=1777 0 0
mount shows the /tmp ramdisk.

df may indicate a /tmp space issue, but the working 64 bit output is the same.

The ramdisk actually works -- example unpacking a zip file in /tmp.
Initial size of tmp:
$ sudo du -s /tmp
12 /tmp
$ cp pebuilder*zip /tmp
$ cd /tmp
$ ls
keyring-KZtBLC orbit-ubfan pulse-PKdhtXMmr18n ssh-bmHFaV1802
orbit-gdm pebuilder3110a.zip pulse-ySSFfpyl52CL virtual-ubfan.QmMTrW
$ sudo du -s /tmp
3320 /tmp
$ unzip pebuilder3110a.zip
Archive: pebuilder3110a.zip
...
$ sudo du -s /tmp
9192 /tmp
Note that the copy and upziped file were not put on the / filesystem
and still do not appear on /tmp.
