Hi,
I tried with the following file:
https://sysprogs.com/getfile/241/CppUTest-3.8r2.vgdbxtfp
MD5 hash is 8305A2229821BED05B14B8FA9B9CBE3D
Note:
I tried again to verify that installing other packages works, I selected the stm MP1 toolchain, which started downloading, after I canceled the download the gui was hung as described above. My main issue is the CppUTest installation, unblocking the gui would be another bonus. By the way: the Embedded Profiler and fast semihosting pakage was a nother instance where the package manager did not work for me.
