This is my problem that faced when upgrade from 2.8.3 to 2.8.4.
You are getting that message because you have the three plugins below installed which all depend on nodebb-plugin-emoji so you cannot remove the main plugin without first removing those
I’ve done it for you anyway 
You should be able to upgrade now.
@cagatay that looks very much like a permissions error. Are you attempting the upgrade as the user running NodeBB ?
Seems to be a permission problem.
test ./nodebb upgrade command with root user. (not good but I have this problem one time ago resolved like this) (Mark will yell at me )
go to normal nodebb user and ./nodebb upgrade again
@phenomlab its very interesting but upgrade is done when i login admin panel and nodebb is working without problem.
so sould i upgrade again by root?
PS: i always use user not root but user has sudo command
@cagatay If the upgrade appears to have worked, then you don’t need to run it again, but I would certainly take a look at the nodebb-plugin-emoji issue in more detail as this is 100% a permissions issue
@phenomlab faced same problem for upgrade to 2.8.5
Mark do you have this plugin on Sudonix? And which version are you running?
@cagatay Yes, I do, but it’s not a version issue - it’s permissions.
@phenomlab permission for user right? so i did not change any permison for nodebb user so why it caused or what i should do for to give permision to nodebb user? till 2.8.2 nodebb user can upgrade any permission case what happened with 2.8.4
@cagatay are you able to remove that plugin and reinstall or does it present the same error?
@phenomlab yeap i removed the plugin and reinstall it problem is fixed.
undefined phenomlab has marked this topic as solved on
@phenomlab i deleted emoji plugin but while upgraded to 2.8.6 faced same problem.
cant understand whats going on.
@cagatay can you provide the logs?
@cagatay does it work if you remove this plugin, perform the upgrade, and then put it back afterwards?
@phenomlab i removed the plugin then upgraded but faced same eror…
Maybe reset permissions on all nodebb directory like this ?
chown -R yournodebbuser:yournodebbuser /home/youruser/yournodebbdirectory
chown -R nodes:nodes /home/nodes/nodebb
because I see permissions error on /home/nodes/nodebb/builds/.... in the last screenshot
And .upgrade and or rebuild nodebb
??
@DownPW yes, but we really need to understand why and how these permissions are changing.
@DownPW @cagatay I found the reason why. This plugin is in fact faulty. I installed it myself because I wanted to add that feature to Sudonix. Not only does it push socket.io through the roof (and adds at least 2 seconds lag to each transaction)
It also is impossible to remove by using the GUI - see my experience below, which is exactly the same as @cagatay
Not great. The only way to remove this cleanly is from the CLI
npm remove @nodebb/nodebb-plugin-reactions
./nodebb build
./nodebb restart
I remember flagging this a while back - it’s here
https://github.com/NodeBB/NodeBB/issues/10582
And here (one I raised)
https://github.com/NodeBB-Community/nodebb-plugin-reactions/issues/8
So, my advice is NOT to use this plugin currently as the unnecessary load it places on your forum isn’t worth the functionality it provides.
@phenomlab i dont have this plugin Mark. So the problem is currently continue.
@cagatay Sorry - my mistake.
