Mastodon installation fails / install script error

[blitzgneisserin]

Context

• Hardware: VPS bought online
• YunoHost version: 11.1.16
• I have access to my server: Through SSH & through the webadmin
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no

Steps to reproduce

Tried to install Mastodon both via webadmin & command line (ssh), but the installation fails while Mastodon is being built. I tried both mastodon in the app catalog + git and always get the same error.

Error: Unable to install mastodon: An error occurred inside the app installation script
Info: The operation 'Install the 'mastodon' app' could not be completed.

Log: https://paste.yunohost.org/raw/kerabomapo

Maybe this is helpful, too:

Please help, I am writing an article about installing Fediverse instances for a well known IT magazine, this used to work reliably a few weeks/months ago. It seems that some time ago other people had the same or a similar issue which was fixed - but why is it not working here? I had a working Mastodon instance some months ago on the same VPS.

This error seems to point to permission issues. Are you installing on a clean yunohost install? Or could it be possible there are still files left that may have wrong permissions? It's not something I have encountered before.

@panomaki clean brand new server, just I set it up yesterday

That discussion is about a different error caused by blurhash. That shouldn't prevent you from installing 4.0.2 as that's been patched to solve this error. (For newer versions see the various issues and pull requests).

I've just done a fresh install and don't get any errors for some reason. What kind of VPS are you installing on?

[blitzgneisserin]

@panomaki I don't have many infos about the hardware. It has 4 GB of RAM, 1 virtual core and 100 GB of SSD storage, seems to be a 64 bit processor, company is easyname.at However, apparently there is no info about the virtual machine software, whether it's wmware or something else. well I will also try another fresh install of the whole system. Btw, setting up Pleroma seems to work without any issues. Anyway, thanks for trying to help. Maybe also worth to mention: apparently the Debian 11 that this company provides for the VPS is tweaked somehow. When I am installing Yunohost, I have to remove several packages, e.g. Apache. I mean I think it's not a regular/official Debian 11 iso that Debian provides, I think it's somehow custom built for a web server or something like that.

@blitzgneisserin That could indeed mean that e.g. ownership of /var/www is different. What is the output of sudo ls -lart /var/www ?

@blitzgneisserin OK, that's not it - looks the same here.

@panomaki thanks for trying to help, I reinstalled the whole system and it worked.
