graphics library installation error

[kohlhase]

I am not sure that this is the right place to report this error, ... running lmh omdoc on MiKoMH/GenCS/source/graphs-trees/en/bbt-size.tex and get the following error

this seems to be a docker installation error to me.

maybe @cmaeder or @m-iancu have some ideas about this.

I have a fix. This can be run to fix it in-place

lmh docker sshell # open a shell in docker, make sure it is running
apt-get update && apt-get -y install perlmagick # install the perlmagick package
exit

I am compiling and updating the docker image right now.

@m-iancu You probably want to use this fix inside MathHub as well

[kohlhase]

@m-iancu I think that this will fix quite a lot of the remaining LaTeXML errors in MathHub. This is good news.

[m-iancu]

perlmagick was already installed on MathHub but there may still be other missing packages. It's good we have the dockerfile for localmh to maintain/document what is needed.
