Hi All, I've tried running Guille's snap package and building my own, but keep getting the same error: $ pharo Pharo.image setlocale() failed (check values of LC_CTYPE, LANG and LC_ALL) could not find display driver vm-display-X11; either: - check that /snap/pharo/x1/usr/bin/pharo-vm//vm-display-X11.so exists, or - use the '-plugins <path>' option to tell me where it is, or - remove DISPLAY from your environment. /snap/pharo/x1/usr/bin/pharo-ui: line 11: 6419 Aborted (core dumped) "$DIR"/"pharo-vm/pharo" "$@" $ ll /snap/pharo/x1/usr/bin/pharo-vm//vm-display-X11.so -rwxr-xr-x 1 root root 265540 Mar 10 17:06 /snap/pharo/x1/usr/bin/pharo-vm//vm-display-X11.so* As can be seen above, the .so file is present. So next guess is that it is missing some dependency, however... $ ldd /snap/pharo/x1/usr/bin/pharo-vm//vm-display-X11.so not a dynamic executable Any suggestions? Thanks, Alistair
