Mount /snap as RW in 18.04 Bionic Beaver

  • 772

I installed PyPy3 via sudo snap install and when I'm installing packages, I get this error:

OSError: [Errno 30] Read-only file system: '/snap/pypy3/2/site-packages/easy_install.py'

I tried finding the mount point and remounting with sudo mount -o rw,remount but to no avail:

mount: /snap/pypy3/2: cannot remount /dev/loop11 read-write, is write-protected.

I want to mount some directories under /snap as RW.

mount snap 18.04

  1. The underlaying snap filesystem (squashfs) is purely read only and cannot be made writable. Perhaps the pypy3 snap needs some love to redirect site packages to $SNAP_USER_DATA where it would be fully writable.
