i cant install anything. VPS UBUNTU SERVER

[saqib4]

hi, i am new to ubuntu, i am connected to my vps through ssh. I am facing a problem and cant install anything on my server. error I am receiving on every installation is




dpkg: unrecoverable fatal error, aborting:
fork failed: Cannot allocate memory
E: Sub-process /usr/bin/dpkg returned an error code (2)



after that when I try to install anything it shows me

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

when i run this command "sudo dpkg --configure -a", it starts installing and abort in the middle with the above error (2).

It would appear that there are only 256 megs of ram available, and no swap. With that small amount of ram, you might have to allocate some disk to swap just so you can operate efficiently. This is done by building a file, say one gig bit, then tell the system to use it a swap.

You will use dd to build the file, mkswap to format it, and swapon to tell the OS to use it. In this example, "swampy" is the name of the file



dd if=/dev/zero of=/swampy bs=1024 count=1048576
mkswap /swampy
swapon /swampy


You'll want to add it to /etc/fstab so it will be used next time you reboot:



/swampy swap swap defaults 0 0


Once that is done, post back errors.
