I am trying to use the suitecloud-cli npm package to authenticate with a netsuite environment. When I run "suitecloud account:setup", I then enter the authid, and the command errors and says "Web browsing is not supported on this device". Any idea how I can get this working? I am on a linux laptop currently.

There is an open issue about this here: https://github.com/oracle/netsuite-suitecloud-sdk/issues/698 The advice in that thread is to use the account:savetoken command which has been removed in the newest version. It might be possible to use the new accountsetupci command but I'm still on the older version so I haven't tested it myself. Alternatively you should be able to downgrade to the latest version which still has the account:savetoken command.

Yeah, I did see that. I dug through the source code a bit and found that the cli is using a jar file. I decompiled the jar file and found the following lines that I think may be the issue.

private void requestCodeGrant(URI authUrl) throws IOException, PKCEException {
        if (!Desktop.isDesktopSupported() || !Desktop.getDesktop().isSupported(Desktop.Action.BROWSE)) {
            throw new PKCEException(Messages.msg_oauth_browser_not_supported);
        }
        if (SystemUtils.IS_OS_LINUX) {
            Runtime.getRuntime().exec(XDG_OPEN_COMMAND + authUrl);
        } else {
            Desktop.getDesktop().browse(authUrl);
        }
    }
