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:

I would like to create a QT GUI package in Noetic. Previously in kinetic/melodic, this could be done using the command 'catkin_create_qt_pkg ' but it's not working in Ubuntu 20.04 as I get
catkin_create_qt_pkg: command not found
Unfortunately, noetic appears to have removed the support for the qt-create and qt-build. Thus, I get 'Unable to locate package' when I try to install them using
sudo apt-get install ros-noetic-qt-build
sudo apt-get install ros-noetic-qt-create
how to create a qt-gui in ubuntu-20.04 with noetic?

I started using a computer at work that has Ubuntu 16.04 installed. Initially, Python3.6.8 was set as the version that was used if I entered the command 'python3' at the terminal. I updated Ubuntu using 'sudo apt-get update', installed miniconda and used the 'sudo apt-get autoremove' command. I followed the mini-tutorial on the anaconda website and one of the commands resulted in a warning about the pip version being old so I upgraded it inside a conda environment.
I noticed at some point that this error was occurring whenever I entered 'python3' at the commandline:
But as you can see, the default 3.5.2 version is there, but for some reason the 3.6.8 version doesn't seem to be there. These are the symlinks in /usr/bin and /etc/alternatives:
Is it safe for me to simply install Python3.6 using 'sudo apt-get install python3.6' and then the symlink will work correctly?
Thanks, any help appreciated.
Jupyter notebook work just fine on my computer, but when i run it via ssh from another computer i receive this message:
ImportError: No module named jupyter_core.command
Im using Ubuntu 18.04.3 LTS for both of them

Ok then.
I just installed Ipython outside of the environment i worked with.:
conda deactivate
and then:
sudo apt install ipython
This worked for me
sudo apt install python3-jupyter-core
I am unable to install Shiny server on my WSL Ubuntu 18.04 LTS
I get the error after I run this line:
wget https://download3.rstudio.org/ubuntu-14.04/x86_64/shiny-server-1.5.9.923-amd64.deb
sudo gdebi shiny-server-1.5.9.923-amd64.deb
This is the error I keep getting:
/var/lib/dpkg/info/shiny-server.postinst: 97: /var/lib/dpkg/info/shiny-server.postinst: initctl: not found
/var/lib/dpkg/info/shiny-server.postinst: 99: /var/lib/dpkg/info/shiny-server.postinst: initctl: not found
Kindly help.
Tried changing the initctl in /var/lib/dpkg/info/shiny-server.postinst to systemctl but it did not help
I followed the instructions on the R shiny server page
This is working as of July,2020. No need to build from source.
wget https://download3.rstudio.org/ubuntu-14.04/x86_64/shiny-server-1.5.14.948-amd64.deb
