I tried updating my Ghost blog hosted on DigitalOcean with the following command ghost update --no-mem-check since initially it was showing me error of low memory (shows available 140 MB but required 150 MB) as was mentioned here
You can upgrade your server to have more memory available or try to add swap, you can follow this tutorial How To Add Swap Space on Ubuntu 18.04 | DigitalOcean I faced this issue in the past and this worked for me
@daburix Well, I retried it again and this time I got this error. I guess, its related to memory but the swap space creation you mentioned is strictly mentioned not to be done on SSD which is what I have. I guess I have to upgrade to higher memory allocation.
@Hannah please do provide a solution if exists to update without memory upgrade.
Unless you’re managing the server yourself (i.e. not through a provider like Digital Ocean or Linode, but rather using your own hardware), this isn’t really something to worry about, especially since you won’t be using the allocated swap often
