I have come across this grave bug as well. I have a Debian sid suite in my desktop machine, regularly updated every other week.
If I try: # apt install libgcc-8-dev I get: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libgcc-8-dev : Depends: libgcc-s1 (>= 1:8.4.0-2) but 10-20200324-1 is to be installed E: Unable to correct problems, you have held broken packages. PS: I noticed this after a full-upgrade, when my former fully functional RStudio program no longer worked. i downloaded its official deb package from RStudio site and it was unable to install, stating that it had dependency problems with libgclang-dev. I tracked down the problem up to libgcc-s1. -- ####################################### Prof. Mauricio Ortiz Calvao Federal University of Rio de Janeiro Institute of Physics, P O Box 68528 CEP 21941-972 Rio de Janeiro, RJ Brazil Email: o...@if.ufrj.br Phone: (55)(21)39387483 Homepage: http://www.if.ufrj.br/~orca #######################################
