can't update to deck 1.1.1

[ulph0]

hi, i hope this is the right place to files this. didn't find this bug. i can't update from deck 1.0.5 to deck 1.1.1 in nextcloud 19.0.4. when i try to, an error message appears: "An error occured during the request. Unable to proceed.
Couldn't update app." this only happens with deck, all other "apps" are updating as usual.

nextcloud.log tells this:

Hmm, that looks odd. It worked fine when installing it just some minutes ago on another instance of mine. Could be that there was an issue with the download. Can you check if it works after having another try?

[ulph0]

dear julius, this doesn't work for me since the update to 1.1.1 came out, so i tried it nearly approx. 20 times the last weeks, while i updated several others including nextcloud versions. now 21 times, but nothing changed. one thing changed; that meanwhile the update to 1.1.2 is out. but unfortuately it still doesn't work.

[juliusknorr]

Do other app updates work fine for you? Could you maybe check if your tmp directory is properly writable by the webserver?

As a reference this is where it fails in the server code:
https://github.com/nextcloud/server/blob/d9015a8c94bfd71fe484618a06d276701d3bf9ff/lib/private/Installer.php#L292-L306

As a side note: you can always manually download the release from apps.nextcloud.com and replace the deck directory manually of course ;)

dear julius, thank you very much, but didn't want to update manually, i wanted to find the solution for my problem, sorry, but that's how mybrain works :)
yes, other app updates worked, none ever didn't work, but fortunately your answer lead my to the solution. since i am running nc on a raspberry 3, i am using tmpfs for /tmp and didn't give it much memory, just 30MB. now i raised that to 60 MB and the update worked like a charme now. thank you very much and have a nice day.
ps: of course an appropriate error message would have helped me to find the solution on my own.

[juliusknorr]

Feel free to open an issue about that in the server repository then 😉

ok. nextcloud/server#23482
