rstudio won't start on ubuntu 20.04

Hi everyone!

I'm having problems with rstudio on ubuntu 20.04: I compiled R 3.6.3 and installed the latest version of Rstudio from the proper .deb package. Whenever I try to launch rstudio from terminal i get this error:

/usr/lib/rstudio/libexec/QtWebEngineProcess: /lib/libm.so.6: version GLIBC_2.15' not found (required by /usr/lib/rstudio/libexec/../lib/libQt5Positioning.so.5) /usr/lib/rstudio/libexec/QtWebEngineProcess: /lib/libm.so.6: version GLIBC_2.29' not found (required by /lib/x86_64-linux-gnu/libasound.so.2)
/usr/lib/rstudio/libexec/QtWebEngineProcess: /lib/libm.so.6: version `GLIBC_2.29' not found (required by /lib/x86_64-linux-gnu/libpng16.so.16)
Trace/breakpoint trap (core dumped)

Many people online suggest to update libc6 but when I try to do that, the terminal says I already have the last version on libc6 (2.31). Do you have any idea?
