Title: [Solved] new llvm19-lib.tcz breaks local mirrors
Post by: GNUser on May 01, 2026, 10:23:43 AM: Hi Juanito, Rich, and friends. I synced my local TCL mirror to the official repo today and I saw an updated llvm19-lib.tcz trickle in along with a few other new or updated extensions.

My TCL laptops are unable to update llvm19-lib when using my local mirror. This command never returns:

If I use the official repo, llvm19-lib can be successfully updated.

There seems to be something about the updated llvm19-lib.tcz that breaks local mirrors. Any ideas?

Strange, but I guess the problem went away on its own somehow.

Post by: GNUser on May 01, 2026, 12:29:22 PM: Hi Juanito. That's not it. I sync the local mirror by manually running rsync on my server. I wait for rsync to finish before I attempt to update my TCL machines that use the local mirror.

I'll keep an eye on this. If it happens again I'll investigate further and will post here.

That 200 looks like it may be an HTTP 200 OK status code. Maybe it's lying?
Also, I Googled that IP address and it came back as blacklisted by a couple of sites.

Yes, 200 means HTTP OK. I agree that it must be a lie here. Good observation.

I use VPN for privacy. A lot of sites blacklist VPN IPs, so finding my IP on a blacklist is not surprising. However, this would not explain my problem--I do not block VPN IPs (or any IPs, for that matter) from accessing my http server.

Post by: GNUser on June 16, 2026, 03:25:24 PM: I had a similar problem today when a different extension was being updated. Based on my http server's logs, I realized that the problem had nothing to do with the specific extension. The problem had to do with broken zsync support in my http server.

If mirror uses http (i.e., not https) and zsync is present on the TCL box being updated (zsync is part of the base system, so theoretically is always present unless user deletes it), then tce-update defaults to using zsync when updating extensions due to this line in /usr/bin/tce-update:
Code: [Select]
[ "$MIRRORPROTO" == "http" ] && [ -n "`which zsync`" ] && USEZSYNC=yes
Once I fixed my http server to correctly handle zsync transfers (see https://forum.tinycorelinux.net/index.php?topic=28140.msg182931#msg182931), then all zsync-related problems went away.

This thread is solved.

Marked as solved.
