I've used the snap package manager to install packages and I'm always getting the same error, even with the simple hello world example:
$ sudo snap install hello $ hello cannot create user data directory: /home/aaa/snap/hello/20: Bad file descriptor Running with sudo solves the problem for the hello program, but why do I even need to do sudo?
BTW, for the other packages (Meshlab, CloudCompare) it doesn't work also with sudo and gives different errors. For example:
~$ sudo cloudcompare.ccViewer mkdir: cannot create directory '/run/user/0': Permission denied No protocol specified QXcbConnection: Could not connect to display :0 The snap version and Ubuntu distro are:
$ snap version snap 2.22.7 snapd 2.22.7 series 16 ubuntu 14.04 kernel 4.4.0-64-generic 1 Answer
Any chance your home directory is an nfs share with no-write-by-root enabled? If so, try logging in as another user that has a local home.
