Hi Hans, Thanks for your answer. I patched install.sh that way *** install.sh Fri Nov 13 19:14:48 2020 --- /usr/local/context/install.sh Sat Nov 14 20:58:00 2020 *************** *** 100,105 **** --- 100,111 ---- fi fi + if test "$SYSTEM" = "OpenBSD" ; then + if test $(grep -c $(uname -r) $PWD/bin/mtx-install.lua)="0"; then + sed -i "/openbsd/s/[0-9]\.[0-9]/$(uname -r)/" $PWD/bin/mtx-install.lua + fi + fi + $PWD/bin/mtxrun --script ./bin/mtx-install.lua --update --server="$LMTXSERVER" --instance="$LMTXINSTANCE" --platform="$PLATFORM" --erase --extras="$LMTXEXTRAS" cp $PWD/tex/texmf-$PLATFORM/bin/mtxrun $PWD/bin/mtxrun I thought this patch might be usefull upstream. It succeeds in patching mtx-install.lua (I checked commenting all the lines below my patch) but somewhere during the install process, this patched $PWD/bin/mtx-install.lua is replaced by the original one and install fails. What else should I do? Best regards, Damien Thiriet
