I have the same problem, tested twice i had bugs
https://bugs.launchpad.net/subiquity/+bug/2049491
https://bugs.launchpad.net/subiquity/+bug/2049486
but installed system is working

[Jeremy Bícha (jbicha)]

I looked through the attached logs and found that apt-get update has an error. (Same for the duplicate bugs except that the duplicate is using an Italian mirror instead of Iceland.)

E: Failed to fetch http://is.archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages File has unexpected size (15427304 != 15428288). Mirror sync in progress? [IP: 176.57.227.242 443]
Jan 16 06:48:21 ubuntu subiquity_log.2363[6528]: E: Some index files failed to download. They have been ignored, or old ones used instead.

That error (which unfortunately happens sometimes) is enough to crash the installer. While this error is at a different place in the install process, it reminds me of https://launchpad.net/bugs/2037008

The error is likely temporary and if you tried the install again a few hours later, I imagine it would probably succeed without error.

[corrado venturini (corradoventu)]

I think the error is due to:
 UdiLog: Error: [Errno 40] Too many levels of symbolic links: '/var/log/installer/ubuntu_desktop_installer.log'
and so in the installes system the /var/log/installer is almost empty
corrado@corrado-n4-nn-0116:~$ ls /var/log/installer
casper-md5check.json media-info
corrado@corrado-n4-nn-0116:~$

[corrado venturini (corradoventu)]

sorry ... the installeD system...

[corrado venturini (corradoventu)]

Repeating the install on same PC the install was successful, no errors, and /var/log/installer is full.

[Leó Kolbeinsson (leok)]

@jbicha Jeremy - will again try in another hour or so and report back.

[Leó Kolbeinsson (leok)]

@jbicha Jeremy -

Retested and yes now no crash - so yes this was a temporary error and the bug should maybe be marked - invalid.

[corrado venturini (corradoventu)]

But why installer uses local archives instead main? This is easyly producing stupid errors.
