Hi, After updating my system to ubuntu 11.04, all sorts of access permissions seem to have changed. In particular, when compiling any ConTeXt document, I get oad otf > loading: /usr/local/texlive/2010/texmf-dist/fonts/opentype/public/lm/lmmono8-regular.otf (hash: lmmono8-regular) load otf > font loaded okay load otf > file size: 66268 load otf > enhancing ... load otf > saving in cache: /usr/local/texlive/2010/texmf-dist/fonts/opentype/public/lm/lmmono8-regular.otf report | lua: compiling /usr/local/texlive/2010/texmf-cache/luatex-cache/context/7625073666844883aa0723352de861b9/fonts/otf/lmmono8-regular.tma into /usr/local/texlive/2010/texmf-cache/luatex-cache/context/7625073666844883aa0723352de861b9/fonts/otf/lmmono8-regular.tmctexluac: cannot open /usr/local/texlive/2010/texmf-cache/luatex-cache/context/7625073666844883aa0723352de861b9/fonts/otf/lmmono8-regular.tma: No such file or directory luac: cannot open /usr/local/texlive/2010/texmf-cache/luatex-cache/context/7625073666844883aa0723352de861b9/fonts/otf/lmmono8-regular.tma: No such file or directory Trying to mtxrun --script fonts --reload, it tells me MTXrun | resolvers: unable to save 'files' in '/usr/local/texlive/2010/texmf-cache/luatex-cache/context/7625073666844883aa0723352de861b9/trees/1240e363db2f4c53de58379d2b0c6f6b.lua' (access error) MTXrun | fontnames: unable to access database cache MTXrun | fontnames: accessing the data table failed and similar errors. I've tried sudo mtxrun [...], but then the command is not found. I hope the problem will be resolved by changing folder permissions, but I'm not sure which folders are affected and which I should refrain from changing. Any help will be much appreciated. Thank you, Severin
