Ubuntu Cannot Read Proc File System

this wole deal seems to me like yet another case of "fixing what's not broken", introducing a ton of unnecessary complication by that. Seriously... In other works, seteuid(), read() -> on fail, seteuid(0) and keep it that way, on success -> setuid() -> permanently drop privs. I assume that the loader was expected to have upgraded between my release revisions but was not upgraded as part of the script or some such issue. more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed http://bovbjerg.net/ubuntu-cannot/ubuntu-cannot-print-pdf-file.php

  2. Problem is: in some cases (specially when you're not using grub, like when using Slicehost/RackSpace Cloud servers), the do_release_upgrade will upgrade everything your system to natty -- everything EXCEPT your kernel

  5. I unfortunately don't have the resources to test this myself currently.

Good Luck! rsyslog isn't using up CPU cycles, but it is failing to read kmsg. Is this the correct command to find it on an Ubuntu Server install? If this succeeds, we know that this will work de-rooted; if this fails, we don't enable kernel-message logging.

I am downloading the 10.04 iso right now and will do a test install in a VM and test it to see of I see a difference.

I couldn't find a simple solution and ended up solving this issue by removing rsyslog entirely and now use syslog-ng which does everything I need (only issue when installing was to check over here The change adds the '#' #$ModLoad imklog # provides kernel logging support (previously done by rklogd) –Richard May 31 '14 at 16:01 add a comment| Not the answer you're looking for? vBulletin 2000 - 2016, Jelsoft Enterprises Ltd.

I don't have a fix, sorry. The solution is to make sure your kernel is upgrade to the most recent version - and that you're actually running it.
