Upgrade problem because AutoInstaller can not remove .ssh directory (InstantSSH)

**FISA4** · May 27th 2014

I´ve tested some plugins on i-MSCP 1.1.8.
As i tried to upgrade to 1.1.9 i got an error message because something was wrong with the InstantSSH plugin.
I didn´t noticed the error message but here is the log:

Code

[Sun May 25 18:01:37 2014] [error] iMSCP::Dir::remove: Unable to delete directory /var/www/virtual/fisa4.de/.ssh: cannot remove directory: Directory not empty

I couldn't login into i-MSCP to remove the plugin, so I deleted it manually in the database.
after that, i could upgrade i-MSCP to 1.1.9 but the .ssh folder is still there and even as root i can not delete the folder.

chmod / chown / rm -rf ... nothing works

Hello ;

Well, first, without the error message from installer, I cannot really say what was wrong during the update and therefore, I'll have to do a test myself to try to reproduce... You removed the plugin manually, meaning that related data were not removed by the plugin (backend side). You must so process manually..

Here, you say that you cannot remove the .ssh directory (including its content), even as root user. It's normal because the /var/www/virtual/fisa4.de directory and the /var/www/virtual/fisa4.de/.ssh/authorized_keys file are protected (immutable bit).

You must so remove the immutable bit on the /var/www/virtual/fisa4.de directory and also on the /var/www/virtual/fisa4.de/.ssh/authorized_keys file as follow:

Shell-Script

# chattr -i /var/www/virtual/fisa4.de# chattr -i /var/www/virtual/fisa4.de/.ssh/authorized_keys

Once it's done, you can normally remove the directory /var/www/virtual/fisa4.de/.ssh

Shell-Script

# rm -r /var/www/virtual/fisa4.de/.ssh

I'm surprised here because you are not a noobs. You should know about the immutable bit possibility.

@FISA4

Can you give me the result of the following command on your system (the one on which you installed i-MSCP)

Shell-Script

# df -TP /var/www/virtual

Thanks

@FISA4

Ok, it's strange because the immutable flags are not supported on you file system normally. I wondering how the flag were applied... Does my previous answer helped you?

**Nuxwin** · May 27th 2014

Ok got it.. In fact, simfs is not a file system... It's a map to a directory on the host (which can support immutable bit).. Well, I'll have to check that...

Your answer helped.

File and folder are removed.

THX.

I'm installing openvz to test anyway...
