I have Ubuntu 20.04 and installed MATLAB 2021b. When I run (does not matter whether or not as root) simulink, it crashes with the error "Inconsistency detected by ../elf/dl-tls.c: 517: _dl_allocate_tls_init: Assertion `listp != NULL' failed!".
Here it says, the problem is with glibc version and it is suggested that version should be changed. But changing the glibc version may create problem within the OS.
Are there any other solutions?
System Info:
Kernel: 5.11.0-37-generic
gcc: 9.3.0
glibc: 2.31

Have you tried this approach:
Installed a local copy of glibc of the recommended version. A local copy is not used by your OS, so you don't need to worry.
Now from a terminal, change your env var LD_LIBRARAY_PATH by inserting the local path as the FIRST. Start matlab from this terminal. This will force matlab to use the local glibc.

No. Two steps here.
  1. Set LD_LIBRARY_PATH. You need to put your local glibc folder as the first one to force matlab to use it. In a terminal: export LD_LIBRARY_PATH=your_local_glibc_path:$LD_LIBRARY_PATH
  2. Then from the same terminal, go to the installation folder of your matlab. Most likely is /usr/local/Matlab<release>. Then type bin/matlab&

This is very disappointing to see in ofiicially supported Ubuntu 20.04 distribution.
There is no other application that needs to downgrade something as used as libc lib.

These are the error messages when I open simulink on Matlab R2021a on my Ubuntu 20.04. I recently installed both the OS and MATLAB.
SlProxy service unavailable.
Error loading /usr/local/MATLAB/R2021a/bin/glnxa64/builtins/sl_main/ /usr/local/MATLAB/R2021a/bin/glnxa64/builtins/sl_main/../../../../bin/glnxa64/ undefined symbol: _Z27FcnCheckAndConvParamToFixPtPK7SLBlockP21_slDataTypeAccess_tagPKvPKclibiPv: Resource temporarily unavailable: Resource temporarily unavailable
I have searched for them online, but couldn't find anything helpful.
Additionally, when I dismiss these messages and try to create a new blank model, I get another error:
Error loading /usr/local/MATLAB/R2021a/bin/glnxa64/builtins/sl_main/ /usr/local/MATLAB/R2021a/bin/glnxa64/builtins/sl_main/../../../../bin/glnxa64/ undefined symbol: _Z27FcnCheckAndConvParamToFixPtPK7SLBlockP21_slDataTypeAccess_tagPKvPKclibiPv: No such file or directory: No such file or directory
I solved it installing an update from the notifications icon of the Matlab home page. Restarting Matlab, now Simulink works successfully.
