[BUG 1] Running /usr/sbin/update-seamonkey.sh probably does not show 'You are already running the latest version' when your SeaMonkey is indeed the latest one.
[CAUSE] There is a readlink command in get_current_version(), an user-defined function in /usr/sbin/update-seamonkey.sh. The argument of that command is a relative path, not an absolute one, and that causes get_current_version() getting wrong data when the working directory of /usr/sbin/update-seamonkey.sh is not the root directory.
[BUG 2] The latest version of SeaMonkey is shown on https://www.seamonkey-project.org/ and it is 2.53.19 for the time being. However, the version of SeaMonkey installed is 2.53.18 after running /usr/sbin/update-seamonkey.sh.
[CAUSE] The archive site of SeaMonkey was moved. /usr/sbin/update-seamonkey.sh still uses the old and obsolete site. Please refer to https://blog.seamonkey-project.org/2023 ... zilla-org/ for the details of archive site migration.
