This is, perhaps, a quite unique setup and potentially the wrong way to do things, but worked with previous versions of SNAP 8.
- SNAP installation sits in /usr/local/snap
- .snap folder sits on a filesystem where all potential runtime downloads are stored (means SNAP doesn’t open HTTP connections on headless server with no internet access)
- symlinks sit in users’ home dirs, e.g., /home/dmckay/.snap → /afilesystem/.snap
- /usr/local/snap/etc/snap.properties and /usr/local/snap/etc/snap.conf are left as installed - i.e., the default user dir and the auxdata folders are not changed.
Previous SNAP versions (since 8.0.4) worked well with this setup, with SNAP finding pre-downloaded auxdata files (dem and S1 orbit files).
SNAP 8.0.9 fails with FileNotFound errors relating to $HOME/.snap/system/ and subfolders of that. e.g., the “lock” file, and $HOME/.snap/system/core/locale/core_snap.jar, which I think it should be getting from /usr/local/snap/snap/core/locale afaik.
My feeling is the symlink method is no longer working. However, I’ve had no success using the snap.conf and snap.properties files to configure this setup.
I’d be grateful for any assistance.
