Rstudio server returns grey page after upgrading R to 4.1.0

[stephaneP]

system info:

• ubuntu 16 up-to-date
• Rserver rstudio-server-1.4.1106-amd64.deb
• I also upgraded all Bioc packages to v3.13

After updates I rebooted the server and still get this error in /var/logs/syslog
I reinstalled the deb => no better
I do not have a .sessions in my home but I issued ** sudo rstudio-server force-suspend-all** without more success

/var/logs/syslog

ERROR session hadabend; LOGGED FROM: rstudio::core::Error {anonymous}::rInit(const rstudio::r::session::RInitInfo&) src/cpp/session/SessionMain.cpp:680

I can start R in terminal without problems
sudo rstudio-server verify-installation does not return errors

• I have the error also when using 127.0.0.1:8787 under VNC on the server

Any idea what is corrupted on my machine and how I can fix this?

Thanks in advance

this may help:

Thanks Martin, I discovered this after posting.
I just tried to install rstudio-server-1.4.1712-amd64.deb over my previous version but got an error while doing it.

sudo gdebi rstudio-server-1.4.1712-amd64.deb

Any idea what this means?
Thanks

[martin.R]

No idea. That's probably a question for an RStudio employee to address.

When I try to start I now get:

sudo rstudio-server start

/usr/lib/rstudio-server/bin/rserver: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

Is it because I still have ubuntu16 or am I missing a particular version of libssl?

A pity that apt update did not warn me before installing R4.1 over 4.0.X !!

My big

I had downloaded the preview for ubuntu 18, it now worked with the correct OSbuild
I can now start my server and access it in my browser, sorry for the noise
