files integrity error .rnd files created after upgrade on Arch Linux

[doronbehar]

Hey guys, I hope it's O.K I've discarded the issue template. I just wanted to let you know that after the last upgrade to 14.0.4, here on an Arch Linux server, I got file integrity errors about files which are not present upstream:

Technical information
=====================
The following list covers which files have failed the integrity check. Please read
the previous linked documentation to learn more about the errors and how to fix
them.

                        )

                )

        )

I fixed the issue by just deleted these .rnd files but it happened to me on previous upgrades as well and as far as I can remember I've encountered similar errors here on the issue tracker.

GitMate.io thinks possibly related issues are #9795 (Upgrade error), #7723 (Integrity Error when upgrading to 13.0.beta4), #1123 (Integrity check failes after upgrading to Nextcloud10), #151 (ERRORS/WARNINGS after Upgrade OC 9.0.2. to NC 9.0.5 "Some files have not passed the integrity check"), and #9751 (File integrity check failed after upgrade from NC 13.0.3 RC1 to RC2).

I hope it's O.K I've discarded the issue template

well, now I have no idea about your setup.

How did you install Nextcloud? Via the "official" Arch package or a Nextcloud tarball?

I use Arch btw.

[doronbehar]

Via the the official package. I use the package upgrade hook suggested in the WiKi - https://wiki.archlinux.org/index.php/Nextcloud#Pacman_hook

Since the official package doesn't contain these .rnd files, my suspicion is that this occ command is the main suspect.

Shall I write all the info requested in the issue template? This is not a crash so there are not many interesting things to find in the logs.. I suppose occ has a verbosity flag? Perhaps I can mimic the version update and run it again with a verbose flag and write here it's output?

[ChristophWurst]

occ does not create these files.

Do you use putty or similar? Ref https://www.openssl.org/docs/man1.1.0/apps/rand.html https://www.howtogeek.com/forum/topic/what-the-heck-is-an-rnd-file

[doronbehar]

Interesting.. I've rebooted my machine and I've checked perhaps if my Apache server is creating these files and I could only notice they didn't got recreated.

[ChristophWurst]

Okay, thanks for your feedback. I'm closing this ticket now.

Should you see those files again, feel free to reopen.

I see this .rnd file as well. I deleted it ran the upgrade and came back. I was on NC15 upgraded to NC15.0.1

Have you seen/read this explanation: https://file.org/extension/rnd
It is created and used by e.g. OpenSSL (binary libcrypto.so.1.1 matches).

[MorrisJobke]

Okay, thanks for your feedback. I'm closing this ticket now.

Closing as per this ^

It has nothing to do with Putty, Apache is creating them because of Nextcloud and/or its apps
