LaTex package “float” broke after texlive 20190830

After updating texlive to the 20190830 version, the “float” package started working, giving ! LaTeX Error: Unknown float option 'H'. even if the same file was compiling correctly before and \usepackage{float} is used.

You need to downgrade at least to the 20190227 version. I did apt purge texlive* then tried to install texlive from the stable distribution (buster is shipping 20190227) but even after having purged everything related to texlive the system could not install that version for broken dependencies/wrong versions. Basically, texlive depends on A that depends on B which is tracked/installed from sid/testing but it wasn’t shown by apt when describing the broken situation.

Any recent version of aptitude should handle this situation well: just run aptitude install texlive -t stable (or just aptitude install texlive with the apt policy pointing to the version shipped by stable) and accept the second solution, downgrading also the libraries causing the broken situation.
