Most likely, updating your system libraries has resulted in the removal of an existing library against which one of the R dependencies was linked when MIRO was installed. You should see an error message similar to this: libicui18n.so.70: cannot open shared object file: No such file or directory… The error message usually also contains the name of the affected R library as well as the path where the library is located. To fix this problem, the library must be recompiled. To force recompilation of one of the R libraries that MIRO depends on, simply remove the directory from the MIRO R library (e.g. rm -r ~/.config/miro-library/2.3/stringi/) and add an empty file named INSTALLING to the root of the library path (e.g. touch ~/.config/miro-library/2.3/INSTALLING). The next time you start MIRO, the library will be recompiled and linked against the updated system library.
