HEADS-UP: Please upgrade Tumbleweed to 20240311 via zypper dup in a TTY

If you are still in that situation, you are better off trying

zypper --no-refresh dup

and install packages still in the cache, if there are some, to complete the upgrade to TW snapshot 20240311.
Then you can use the regular “zypper dup” to get the two other snapshots that have been published meanwhile.
