Netselect fails when not using large files and prevents install script from being rerun

[clotodex]

Using netselect to choose the top4 hosts, in blocks of 10. 20 of 20 blocks complete.te.
Traceback (most recent call last):
  File "/usr/lib/python-exec/python3.11/mirrorselect", line 57, in <module>
    MirrorSelect().main(sys.argv)
  File "/usr/lib/python3.11/site-packages/mirrorselect/main.py", line 386, in main
    self.change_config(fsmirrors + urls, options.output,
  File "/usr/lib/python3.11/site-packages/mirrorselect/main.py", line 107, in change_config
    hosts[i] = hosts[i].decode('utf-8')
               ^^^^^^^^^^^^^^^^^^^^^^^^
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe2 in position 42: invalid continuation byte

After unmounting the disk and restarting the install I get

[+] Applying disk configuration

Error: Partition(s) 3 on /dev/nvme0n1 have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use.  As a result, the old partition(s) will remain in use.  You should reboot now before making further changes.

Do you still have the .conf file around that you used? The netselect error looks like an upstream issue with the mirrorselect packet, and should resolve itself with a new stage3.

Was indeed an upstream bug and has been fixed (to my knowledge) in the meantime.
