Comment (by barracuda156):

 From another PR:
 {{{
 Error: The following dependencies were not installed because all of them
 have unmet dependencies (likely due to a dependency cycle): R-Hmisc
 R-data.table
 Build of dependency 'R-qgraph' with variants '+gcc12' failed, aborting.
 Processing dependencies for 'R-IsingFit' failed, aborting.
 }}}

 {{{
 --->  Dependencies to be installed: R-memisc R-data.table
 Error: The following dependencies were not installed because all of them
 have unmet dependencies (likely due to a dependency cycle): R-memisc
 Build of dependency 'R-mclogit' with variants '' failed, aborting.
 Processing dependencies for 'R-abn' failed, aborting.
 }}}

 Needless to say, everything worked fine earlier with all these.
