Hardware: VPS bought online
YunoHost version: YunoHost 3.7.1.3
I have access to my server : through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
Hi everyone I get an error when I want to install mastodon from the Yunohost admin interface.
Here is the log file of installation
Meh, sorry about that, not sure why we didn’t spot this earlier …
I proposed a fix here : https://github.com/YunoHost-Apps/mastodon_ynh/pull/221
I you can you can try to install the app with the fix included using :
yunohost app install https://github.com/YunoHost-Apps/mastodon_ynh/tree/alexAubin-patch-1
I just realize i can’t install other apps same error of the end
I try to install Mobilizon App getting same error
here is log file : https://pastebin.com/GvxcTKCi
Ugh wtf why didn’t we spot this either …
Anyway, it’s indeed the same issue because it also uses yarn … So bit unlucky here
Made a fix here https://github.com/YunoHost-Apps/mobilizon_ynh/pull/56
You can try it with
yunohost app install https://github.com/YunoHost-Apps/mobilizon_ynh/tree/alexAubin-patch-1
Other apps should be okay though :s
wow lucky shot i picked that app randomly to see if other applications can be installed or not 
Hmf I was absolutely wrong about the origin of the bug and my fix was in fact un-fixing another bug. (Sorry, did all this in a rush)
Anyway … It definitely has something to do with yarn … My new guess is that yarn is already installed from debian vanilla repos, but we need a more recent version (from dl.yarn.org or whichever repo the script uses) but it doesnt upgrade to that version because of the already installed version. If that’s confirmed, that’s a tricky bug in our helpers …
I don’t know if that means anything to you but anyway, would be interesting if you can try to run (on SSH) :
apt policy yarn
And try to remove yarn (assuming it’s indeed installed) :
apt remove yarn
though be careful not to accept too fast as it may be required by something else. If that’s the case, we’ll see what’s the right way to proceed…
i tried this
apt policy yarn
output:
yarn:
Installed: (none)
Candidate: (none)
Version table:Hmmmwokay my guess was wrong again xD
What if you run 'yarn --version' ? Does it say anything ?
Can yarn cause this error because it has been deleted?
output:
-bash: /usr/bin/yarn: No such file or directory xd
I restarted the server and now say
-bash: yarn: command not found
Should i reinstall yarn now?
Just to confirm, I’ve just installed mastodon_ynh on a fresh YunoHost and installation is working fine…
And to check yarn version, I had to first do:
PATH=/opt/rbenv/shims:/opt/rbenv/bin:/opt/node_n/n/versions/node/10/bin:/opt/node_n/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
And then yarn --version give me 1.22.4
@b0hem14n : soooo what if you try to run
PATH=/opt/rbenv/shims:/opt/rbenv/bin:/opt/node_n/n/versions/node/10/bin:/opt/node_n/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin yarn --version
What’s puzzling me is that the original log gives no mention of any install of yarn … Like there’s some things happening with adding the extra repo but never does apt tell about installing/configuring yarn as if it was never installed … Which seems to suggest it’s already installed somehow … But apparently it’s not ? So … x_x
@Aleks don’t need sir i think because i removed yarn and I ran installation of mastodon.It’s will work i guess process in progress atm. I will write when completed
Mobilizion successfully installed
Mastodon successfully installed
