I'm working on a pretty big document with a lot of usepackage and custom commands. I'm using texlive 2018 on both my laptop with Linux Mint 17 and my desktop with Windows 10.
After updating texlive on Linux, the file does not compile anymore, and I get many errors for most of the tables and a forest tree in the document. I completely reinstalled it, but compilation still fails.
The file still compiles on my Windows pc, whose texlive installation has been updated a few days ago.

Here is a not-quite-minimal example:

documentclass{book}



usepackage[utf8]{inputenc}

usepackage[T1]{fontenc}

usepackage[english]{babel}

usepackage[dvipsnames,table]{xcolor}



begin{document}



frontmatter

tableofcontents



mainmatter



begin{table}[h]

    begin{tabular}{lp{8.8cm}}

        x & y \

        x & y \

    end{tabular}

end{table}



backmatter

end{document}

And here is the error log:

Use of @startpbox doesn't match its definition. begin{tabular}{lp{8.8cm}}

Extra }, or forgotten endgroup. begin{tabular}{lp{8.8cm}}

Use of @startpbox doesn't match its definition. begin{tabular}{lp{8.8cm}}

Extra }, or forgotten endgroup. begin{tabular}{lp{8.8cm}}

Extra }, or forgotten endgroup. begin{tabular}{lp{8.8cm}}

Extra }, or forgotten endgroup. begin{tabular}{lp{8.8cm}}

Missing # inserted in alignment preamble. begin{tabular}{lp{8.8cm}}

Missing { inserted. x & y

Missing } inserted. x

Missing } inserted. x

Missing } inserted. x

Missing { inserted. x & y

Missing } inserted. end

Missing } inserted. end

Missing } inserted. end

I'm using this command to compile:

pdflatex -synctex=1 -interaction=nonstopmode %.tex

I noticed that by replacing the column specification with {ll} I don't get any error. Also, removing the xcolor package solves the problem, at least on this MWE, but it can be it's fault as it is still an old 2016 version. Does anyone know which package may cause this problem?

Finally, here's a truly minimal MWE:

documentclass{book}

usepackage[table]{xcolor}

begin{document}

begin{tabular}{p{1cm}}

        x

end{tabular}

end{document}

The table option of xcolor load the colortbl package. Unfortunately this package had an error (or was missing a few bits after the array package was updated). The correct version is now available on CTAN and through the latex package managers.
