RStudio Server (community) can't find libR.so even though it is in path

Note: I have filed this as an issue, but I'm not sure if it is really a bug or just something I need to resolve about my system configuration.
This seems to be a library that causes many people trouble with RStudio and RStudio Server. Often people can fix the problem by reinstalling the core R libraries with apt or manually copying or linking the libR.so file to a place where RStudio finds it.
In my case, I'm using a Conda instance for my R executable.
My instance was working and stopped after upgrading my ubuntu 22.04 VM. I tried some things to fix the problem but have not succeeded.
System details
RStudio Edition : Server
RStudio Version : 2022.07.2+576 (Spotted Wakerobin) for Ubuntu Bionic
OS Version : Ubuntu 22.04.1 LTS
R Version : 4.1.3 (2022-03-10) -- "One Push-Up"
Describe the problem in detail
I have a GCP VM running ubuntu 22.04 which I use for RSS.
I did a sudo apt update && sudo apt dist-upgrade and a restart. RSS stopped working. I ran sudo rstudio-server verify-installation and received
/usr/lib/rstudio-server/bin/rsession: error while loading shared libraries: libR.so: cannot open shared object file: No such file or directory
I decided to reinstall RSS using:
wget https://download2.rstudio.org/server/jammy/amd64/rstudio-server-2022.07.2-576-amd64.deb
sudo gdebi rstudio-server-2022.07.2-576-amd64.deb
and did not receive any errors during installation. However I received the same error as above with verify-installation. I then tried doing conda update --all -y. This also did not fix the problem.
Here is some useful information:

Unable to install libgit2 library on AMI ec2 instance

I am trying to install devtools in a R ami on an amazon ec2 instance. However, before devtools, I need to install some variation of a libgit2 library as a dependency. Given that the amazon distro is red hat, I've tried to install the libgit2-devel variation with the command
sudo yum install libgit2-devel
everytime i get a error message that the package is not available. I have no idea why this is happening.

unable to install DPDK in Devstack(in Ubuntu 16.04 version)

I am trying to install Devstack with DPDK in Ubuntu 16.04. I have installed Devstack (Rocky version) in Ubuntu machine.
Reference link to install the devstack is mentioned below.
https://docs.openstack.org/devstack/latest/
Devstack was successfully installed. However, i am trying to validate DPDK in it.
When i check the status of both DPDK and openvswitch. It is showing the status of openvswitch alone.
Can anyone, please let me know how to install dpdk manually or along with Devstack?
I haven't tried devstack with ovs-dpdk, but if you are using ovs which is compiled with dpdk, then you can start from 'setup Hugepage' section in following doc manually:
http://docs.openvswitch.org/en/latest/intro/install/dpdk/
I also notice networking-ovs-dpdk plugin which can be used in devstack.

Zookeeper set up for Kaa

I'm trying to set up kaa v0.10.0 on ubuntu 14.04 LTS. To install zookeper I used the following command.
sudo apt-get install zookeeper
But it fails to start when I start the kaa-node service.
But when I install the package zookeeperd (seen in older kaa versions documentation sudo apt-get install zookeeperd), it works fine.
Can anyone please clarify which is the correct zookeeper package for kaa 0.10? - zookeeper or zookeeperd
From few of my experiences in deploying Kaa, I don't think Zookeeper will start automatically after installation, perhaps you can start it manually before starting Kaa-node.

You could try running: rpm -Va --nofiles --nodigest
led by skipping the same
