Hi,
I’m following the guide to upgrade the monitoring agent https://www.digitalocean.com/docs/monitoring/how-to/upgrade-legacy-agent/
However when I run
sudo apt-get purge do-agent
I get
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
I run the command as instructed and then re-run the first command but that results in

@KDSys unfortunately the dry-run gives us another error:
dpkg: dependency problems prevent removal of debconf-i18n:
ubuntu-minimal depends on debconf-i18n.
dpkg: error processing package debconf-i18n (--remove):

Hi @KDSys,
Sorry for the long delay in getting back to you. Unfortunately we’re still in the same situation after adding those additional sources:
dpkg: error processing package debconf-i18n (--configure):
package debconf-i18n is not ready for configuration
cannot configure (current status 'half-installed')
Errors were encountered while processing:
debconf-i18n
E: Sub-process /usr/bin/dpkg returned an error code (1)
Hi @Workshed,
You get the error as there is no memory for the process to allocate
dpkg: unrecoverable fatal error, aborting:
fork failed: Cannot allocate memory
E: Sub-process /usr/bin/dpkg returned an error code (2)
This happens when your server does not have enough memoryor SWAP configured.
Do you by any chance have SWAP configured for these cases? If not, let’s configure it and see if the issue would still appear.
First see if you have swap
sudo swapon --show
If the output is empty, it means that your system does not have swap space enabled.
Creating a Swap File
Start by creating a file which will be used for swap:
sudo dd if=/dev/zero of=/swapfile bs=1024 count=1048576
Set the correct permissions by typing so that only the root user can write to the file:
sudo chmod 600 /swapfile
Use the mkswap utility to set up a Linux swap area on the file:
sudo mkswap /swapfile
Activate the swap file:
sudo swapon /swapfile
Now, if you wish for the SWAP file to be there even if you reboot the droplet open the /etc/fstab file:
sudo nano /etc/fstab
and paste the following line:
/swapfile swap swap defaults 0 0
Once you have SWAP configured, please try again to run the command.
Please note this takes 1GB of your droplet’s Disk Space.
Regards, KDSys
