Solution to 'malformed macro definition' and 'DEBCONFsomethingDEBCONF found in exim configuration'

Upgrading a working server application is always tricky. This is especially true if the upgrade had changes in configuration files and you had customizations done in your local configuration file. The recent exim4 upgrade to version 4.67-3 had structural changes in the configuration files. The suggested upgrade method is to accept all the modifications provided by the upgrade and redo the customizations. But what if you did not read the instructions properly and ended having an exim4 installation that throws out errors every time you try to start exim4.

The common error that you could get is

DEBCONFsomethingDEBCONF found in exim configuration

If somehow you get around the above error you might come across the following one

/var/lib/exim4/config.autogenerated.tmp: malformed macro definition

If you read the documentation correctly you will see that the first one is because the update-exim4.conf script checks for lines with DEBCONF inside the configuration file. If the configuration file template or the split templates were processed correctly then these should have been replaced during the generation of the configuration file in /var/lib/exim4. The cause of the problem is that during the upgrade you did not allow the application to accept the modifications in the new version and left the old configurations files as they where.

The simplest solution to the problem is to take the exim4 deb packages, extract them and take out the pristine configuration files from inside them and replace the /etc/exim4/conf.d folder (if you use the split template option) or replace the exim4.conf.template(if you use the single file configuration file option). Make sure you back up the old files before you replace the originals. Now you do a compare with the old files and identify all the customizations that you had made inside them and port these customizations to the new configuration file. Once you are done you should be able to restart exim4 without any configuration file errors.

Once the server is up and running, monitor all the functionalities to make sure that everything is running as it is supposed to before you relax. You should be careful with custom access control rules or custom header overwrite rules that decide your normal operations. Also let your users know that you have made an upgrade and that they might face problems as a preemptive bail :-)

The public's ignorance is their misbegotten gain, and any genuine response is muted and rare. This page, for example, touches on only part of the issue, leaving out critical weaknesses. How, for example, do you protect thumbdrives from the most likely source of infection when plugging into a public internet cafe computer (most of which lack good firewalls)? Holding down the shift key is a method already obsolete perhaps, since activating the shift key when loading a thumbdrive simply locks the host computer. Best response to this problem is to buy a WRITE PROTECT thumbdrive so only you can write on it and no one else. Everything else, including most of what's written, is simply a marketing ploy to assuage consumers and keep them sinking millions of dollars into firewalls and spyware protection (most of which is spyware anyway and therefore ethically most industry today. This ubiquitious problem reflects just how unhealthy our culture has become in many ways. I say, leave the public alone and let them have their privacy if they need it. You don't have to pull people's teeth just to see what's underneath them. Add new comment

Wait through all the Bill-messages until you get the first prompt. Choose R to repair an existing installation. It will search and prompt the Windows installation, showing : 1) C:\WINDOWS choose 1, and it will ask for the Admin password. If you have one enter it or just press Enter. C:\WINDOWS> Now, type C:\WINDOWS> CD .. C:\> FIXBOOT C: C:\> FIXMBR C:\> BOOTCFG /rebuild After the BOOTCFG, it will ask if you want to add the Installation it found, and to be safe answer "Y".

Now we need to tell grub where are the grub files: If you know where they are, type something like: root (hd0,1) else if you have no idea, type: find /boot/grub/stage1 and then the root command with the correct parameters: setup (hd0) to install it on hd0, that is MBR of the first HD. type quit and reboot. The menu will appear again. If you want to make some changes to the boot menu, you must edit the file: /boot/grub/menu.lst $ gksu gedit media/disk/boot/grub/menu.lst sagar raythatha (not verified) access_time 20 Aug 2019 - 23:21 Hey all you can find best solution of this problem over here: Add new comment
