Comment 77 for bug 1157643

Hi,

I had (before update) Ubuntu 12.04.2 LTS (GNU/Linux 3.2.0-41-generic x86_64). I did

sudo apt-get update
sudo apt-get dist-upgrade

The system proposed some updates and one of them was also procps

Get:32 http://nl.archive.ubuntu.com/ubuntu/ precise-updates/main procps amd64 1:3.2.8-11ubuntu6.2 [235 kB]

At the end of the procedure the machine returned

E: Sub-process /usr/bin/dpkg returned an error code (1)

If I look at /var/log/upstart/procps.log I see this error

error: "Invalid argument" setting key "net.ipv4.tcp_mem"

This is a consequence of a file /etc/sysctl.d/30-iscsitarget.conf which has a line

net.ipv4.tcp_mem=1048576

I changed it to

net.ipv4.tcp_mem=1048576 127649 191472

like #54 and #55 suggested.

Then I ran

sudo apt-get -f install

and everything finished OK. So the whole thing seems like a broken iscsitarget configuration file? This is critical because it seems that without procps the update process cannot finish and we're stuck with non functional machines. After the update I have
#lsb_release -rd
