pacman error OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 0

error: failed retrieving file 'libvlc-3.0.21-9-x86_64.pkg.tar.zst' from archlinux.thaller.ws : OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 0
so basically this error message showed but the pkg still makes its way to be installed just good , thats the second pkg that did this move , i dont know if its an issue inmy side or the devs side , note that i have a firewall runing could it be the caused by UFW firewall ? it happend for one packade yesterday , and again for libvlc pkg

This is from libcurl. Or do you use a custom xfer client?

What protocol? http/s or rsync?
Do you maybe use a VPN next to the firewall?
What if you lower the MTU?

https://github.com/curl/curl/issues/13389
If this isn't deterministic (the same url works on a second try) there's probably a transmission error.
Is your network connection generally flaky?

In doubt you'll end up w/ a broken package in the cache, but the signature verification will fail and you get an error and the package won't be installed.
(Even if it could be extracted)

So there's no immediate security risk, but you want to check what's driving this and whether the connection gets intercepted somewhere.

.

No , it generally fine , the seallt thing here is my security setup , prpablly UFW is doing this , or it could be :

sysctl.d from the archwiki page of ipv6 :
# Enable IPv6 Privacy Extensions
net.ipv6.conf.all.use_tempaddr = 2
net.ipv6.conf.default.use_tempaddr = 2
net.ipv6.conf.nic.use_tempaddr = 2

and interstingally i find this one :
kernel.kexec_load_disabled = 1
it could cose some perl problems , but i dont think there is relation between openssl & perl here

In doubt you'll end up w/ a broken package in the cache, but the signature verification will fail and you get an error and the package won't be installed.

i hope not , today it happen again , it was for vim this time , its binary after update lunches fine , wich is wierd , i hate those unpredictable types of issues.

So there's no immediate security risk, but you want to check what's driving this and whether the connection gets intercepted somewhere.

yeah this thing is very wierd , i well see if the presist
