yum install packages-microsoft-com-prod - out of memory error

I am trying to install powershell on CentoOS 8. I follow the official Microsoft instructions.
I had some previous issue.


I rented a nanode from Linode which is the smallest model. I get memory error:

[[email protected] ~]$ sudo yum update

              total        used        free      shared  buff/cache   available
Mem:            821          77         648           1          95         633
Swap:           511          75         436

It is a fairly small node so I resized the node to the next bigger tier and the same error happens

[[email protected] nginx]$ sudo yum install -y powershell
packages-microsoft-com-prod                                                                               25 kB/s | 2.9 kB     00:00

[[email protected] nginx]$ free -m
              total        used        free      shared  buff/cache   available
Mem:           1829          83        1663           1          82        1631
Swap:           511          85         426

At this point, I highly doubt it has something to do with the size of the node. Does anyone know why this could happen?

This is a pretty curious issue. I gave it a shot and I wasn't able to replicate this particular error. If you have any other services running on your Linode they might be using up your available memory.

I would recommend auditing your running services with the command top -bn 1 | head -15 You may also get some useful output from vmstat 1 10 which provides more details on the usage of available memory, as well as swap and cache.

I would also recommend double checking your logs for any clues.

If you can provide any additional details, such as OOM killer messages, be sure to provide it here so we can take a closer look.
