CRC failed on file nextcloud-23.0.12.zip

Hello, I have an old Nextcloud version that I’m going through each upgrade revision one at a time from the CLI occ upgrade command and trying to get to the latest version.

21.02 → 21.0.9 → 22.2.10 → 23.0.12

However, I am on version 22.2.10 and cannot upgrade to 23.0.12 because of a CRC error on the file located at: https://download.nextcloud.com/server/releases/nextcloud-23.0.12.zip

I downloaded on my Windows box and confirm testing with 7zip that there is a CRC error on this file. Who do I contact to see if they can re-upload nextcloud-23.0.12.zip to that distro location?

Thanks

I can confirm. The nextcloud-23.0.12.zip hashes do not match with the provided ones on the download server but the nextcloud-23.0.12.tar.bz2 matches!

I would advice to run the upgrade step to 23.0.12 manualy using nextcloud-23.0.12.tar.bz2 like described → here ←

These are the steps to download the file and check the integrity:

version='23.0.12'
archive="nextcloud-$version.tar.bz2"
server='https://download.nextcloud.com/server/releases'
wget $server/$archive
# check integrity of downloaded file 
for hash in md5 sha256 sha512; do
    [ "$(eval ${hash}sum $archive | awk '{print $1}')" = "$(curl -s $server/$archive.$hash | awk '{print $1}')" ] && echo "$hash match" || echo "hash mismatch"
done

If you copy and paste the above code in your terminal, you will have the file nextcloud-23.0.12.tar.bz2 in your working directory and the check should have echoed:

md5 match
sha256 match
sha512 match

Now you can do the manual update from the code like described in the above linked manual.

Hope this helps,
much luck!

Thank you ernolf for your quick reponse and solution to try. I will have to schedule downtime for next weekend to attempt this again. I appreciate your guidance and will update if successful or not. Thanks!

Btw. You can also download the latest minor release of a major version by using latest-$version.tar.bz2. That way you don’t have to know the exact version number of the latest minor release…

Example for version 23:

wget https://download.nextcloud.com/server/releases/latest-23.tar.bz2

…this should then translate to the following, if you are using the steps posted by @ernolf:

version='23'
archive="latest-$version.tar.bz2"
server='https://download.nextcloud.com/server/releases'
wget $server/$archive
# check integrity of downloaded file 
for hash in md5 sha256 sha512; do
    [ "$(eval ${hash}sum $archive | awk '{print $1}')" = "$(curl -s $server/$archive.$hash | awk '{print $1}')" ] && echo "$hash match" || echo "hash mismatch"
done

@lildude97 @ernolf Did you notify the guys from Nextcloud? Either a bug report on Issues · nextcloud/server · GitHub
or if you consider it a potential security issue: security@nextcloud.com

Ernolf, you are the BEST! I manually downloaded the .tar.bz2 version and unzip and manually installed based on the article and I was able to proceed to upgrading through the next versions and so forth. I am on version 25.0.9 now thanks to you and still upgrading upwards. You are a life saver and you went beyond and help report the bug too! I can’t thank you enough and to bb77 also for advising on some additional tips.
