4. apt install io.elementary.installer

Expected Behavior

Should be able to select Install and Erase Entire disk, but it doesn't show any partitions.

Log Output

** (io.elementary.installer:9521): CRITICAL **: 07:20:11.347: CheckView.vala:105: Unable to get disks list: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying

Hardware Info

These are just my thoughts but it seems like the problem is occurring around this portion of the code in the src/Views/DiskView.vala file

public async void load (uint64 minimum_disk_size) {
        DiskButton[] enabled_buttons = {};
        DiskButton[] disabled_buttons = {};

        InstallerDaemon.DiskInfo? disks;
        try {
            disks = yield Daemon.get_default ().get_disks ();
        } catch (Error e) {
            critical ("Unable to get disks list: %s", e.message);
            load_stack.set_visible_child_name ("disk");
            return;
        }

(Code around line numbers 125-136. Due to the log ** (io.elementary.installer:9521): CRITICAL **: 07:20:11.347: CheckView.vala:105: directly referring to the statement in the try-catch block: Unable to get disks list:)

or the code around line number 47-60. I also suspect that the DBUS_TIMEOUT_MSEC is not sufficiently high. These are just my suspicions as the code does refer to that variable around line number 55.

daemon.g_default_timeout = DBUS_TIMEOUT_MSEC;

Could this be a problem with with Distinst?

[aerocyber]

Maybe, as the installer uses distinst.

[patx]

@aerocyber Maybe using a different installer e.g. ubiquity would work. Is this possible to sudo apt install ubiquity and use that or is there more setup required, need a work around until I figure this out and I'm 75% sure its distinst because POP fails as well. I have made an issue report on the distinst repo as well.

[aerocyber]

I am not sure of it.

[israelpattison]

This is still a problem in 7.1. Same as previously described.

[dvilelaf]

Can confirm

[guzman109]

As @israelpattison and @dvilelaf have mentioned, still a problem. Ubiquity sees the SSD but crashed when trying to install.

I tried again today same Macbook 12" same problem. This is real bummer hope we can get it fixed!

I also have started an issue on the distinst repo related to this pop-os/distinst#316
