yes, all cocalc projects run under the same user "user" in their own container. $ echo $USER user $ id uid=2001(user) gid=2001(user) groups=2001(user) > Does that perhaps mean that some users have no write permission to > it? No, /home/user is a read/write mounted volume and ~/.sage is a directory inside of it. i.e. $ ls -ld ~/.sage drwx------ 14 user user 20 Aug 19 2018 /home/user/.sage $ touch ~/.sage/foo $ ls -l ~/.sage/foo -rw-r--r-- 1 user user 0 Jul 12 17:38 /home/user/.sage/foo > That would explain why the files are missing (because they are > created when missing, which requires write permission). Is there a way to explicitly trigger the creation of such a file?

No, users cannot write to /ext. But DOT_SAGE points to /home/user/.sage, which is read-write, though. $ sage -c 'print DOT_SAGE' /home/user/.sage/ $ sage -c 'matrix(GF(25), [[1]])' p025.zzz: No such file or directory Traceback (most recent call last): [...] -- You received this message because you are subscribed to the Google Groups "sage-support" group.
