Collected errors:
 * copy_file: unable to open `/etc/group-opkg.backup': Read-only file system.

 * pkg_write_filelist: Failed to open //usr/lib/opkg/info/base-files.list: Read-only file system.

This leaves things mounted read-only, too, which breaks other things until a reboot or other manual intervention.

The package feed has been fixed. Reboot the router and try again.

After rebooting and running opkg update, I get no output from opkg list-upgradable. Is that what you were expecting?

Updates to curl,mbedtls,tor,wireguard and a few other packages were made.

Just before I filed this bug, I successfully installed upgrades to a bunch of luci* packages (e.g., luci-ssl went from git-20.216.62123-9f91ff6-1 to git-20.220.55738-b91cc1a-1). I haven't upgraded any packages since then. In particular, I haven't seen an upgrade to libmbedtls12 (which is at 2.16.7-1). I don't have curl, tor, or wireguard installed (though it's offering me versions 7.66.0-3, 0.4.3.6-1, and 1.0.20200729-1, respectively).

I guess my question now is: Should I have got an upgrade to base-files (now at 204.2-r501+69-19b1d5de8b) at any stage, or should my router have never been offering me an upgrade to that package?
