OS: Linux (Ubuntu 20.04.3) /opt/context-lmtx and all directories and files in it are owned by user and not root. I've had this problem before but forgot how to deal with it and neglected to make a not of it. I deleted all old context files and did a fresh install of context-lmtx without su priveledges today. When attempting to typeset a lmtx source file I get an 'unknown script' error. Here's what pops up on my display screen: $ context simple-example.lmtx resolvers | resolving | configuration files already identified resolvers | resolving | loading configuration file 'selfautoparent:/texmf/web2c/texmfcnf.lua' resolvers | resolving | resolvers | resolving | locating list of '/opt/context-lmtx/tex/texmf' (runtime) (tree:////opt/context-lmtx/tex/texmf) resolvers | methods | resolving, method 'locators', how 'uri', handler 'tree', argument 'tree:////opt/context-lmtx/tex/texmf' resolvers | trees | locator '/opt/context-lmtx/tex/texmf' found resolvers | resolving | hash '/opt/context-lmtx/tex/texmf' appended resolvers | resolving | resolvers | methods | resolving, method 'generators', how 'uri', handler 'file', argument '/opt/context-lmtx/tex/texmf' resolvers | expansions | using cached scan of path '/opt/context-lmtx/tex/texmf', branch '/opt/context-lmtx/tex/texmf' resolvers | methods | resolving, method 'generators', how 'uri', handler 'file', argument '/opt/context-lmtx/tex/texmf' resolvers | expansions | using cached scan of path '/opt/context-lmtx/tex/texmf', branch '/opt/context-lmtx/tex/texmf' resolvers | resolving | resolvers | resolving | not saving runtime tree '/opt/context-lmtx/tex/texmf' resolvers | resolving | not saving runtime tree '/opt/context-lmtx/tex/texmf' resolvers | resolving | remembered file 'mtx-context.lua' resolvers | resolving | remembered file 'mtx-contexts.lua' resolvers | resolving | remembered file 'mtx-context.lua' resolvers | resolving | remembered file 'mtx-t-context.lua' resolvers | resolving | remembered file 'mtx-t-contexts.lua' resolvers | resolving | remembered file 'mtx-t-context.lua' resolvers | resolving | remembered file 'context.lua' mtxrun | unknown script 'context.lua' or 'mtx-context.lua' # END Can anyone shed some light on how this should be handled?
