Failed to update Zotero after changing permission with chmod 707












4














I am running Ubuntu 16.04 LTS and I have installed Zotero adding the PPA, following the instructions in this page. It worked all well, but when I try to get any update, I get the following error message:



enter image description here



In order to "modify the Zotero program directory to be writable by your user account" I applied sudo chmod 707 zotero, as described here and, as far as can see from the screen shot below (which was generated by the command ls -lg /usr/bin), the changes took place successfully:



enter image description here



Is there anything wrong with this terminal output? Shouldn't I have reading, writing and execute (rwx) permissions for user, according to this output?

          With that command you only changed the permissions for the executable file, not for all the files the program uses (and probably needs to update).



          I recommend that you chmod the /usr/bin/zotero file back to 755 and instead run the Zotero updater with sudo and it should have the rights needed to update itself.



          EDIT: It is recommended to run sudo su to open up a root shell and then just run zotero as a command line command to open it with root rights. Directly running sudo zotero is not recommended because it uses your real home directory and you may end up with root-owned files in your home directory.

            @BCArg Assuming the Updater fires up as soon as you launch zotero, it should be enough to run sudo su to open up a root shell and then just run zotero as a command line command to open it with root rights. Directly running sudo zotero is not recommended because it uses your real home directory and you may end up with root-owned files in your home directory.

            @ Tim Schumacher. Thanks for the reply. When I ran sudo su then zotero a message dialog with the following messaged popped-up: "you appear to be running Zotero as root. This is insecure and may prevent Zotero from functioning when launched from your user account. If you wish to install an automatic update, modify the Zotero program directory to be writeable by your user account.". Do you think it is safe to continue? Anyways, the updates are not that important for me by now.

            @BCArg The problem with changing the permissions for that directory (and all subdirectories and files) is that you probably won't be able to restore the original permissions on all files. As we changed the home directory to /root by running sudo su (instead of just running sudo zotero as the program seems to assume), it should all be fine if you continue and let it run the update.

          • @ Tim Schumacher: thanks for the comments, but I think I will leave the update off. Zotero is running fine and, most importantly, this is not my own computer, otherwise I would assume the "risk".

          You'll want to also change the permissions of the /opt/zotero folder by running:



          sudo chmod 707 /usr/bin/zotero && sudo chmod -R 707 /opt/zotero

            why 707? I can't think of any good reason for that...

          I just resolved the issue by changing ownership of ~/zotero directory and successfully upgraded from Zotero Help>Check for Updates... link. For some reason, previous ownership was held by 501, which is held by OSX user.



          sudo chown -R <username>:<username>  ~/zotero

            This depends on how (and where) did you install Zotero. I used the smathot/cogscinl repository to install mine (full installation instructions):



            sudo apt-add-repository ppa:smathot/cogscinl


            If this is your case, you will probably find your Zotero directory in /opt/zotero. You need to change the permission to the user that will update Zotero, basically this:



            sudo chown USERNAME /opt/zotero

              In Ubuntu 16.04, I did the following:





              1. In the terminal execute Zotero as root



                sudo zotero



              2. Enter the password and press Continue to the following message



              Press Continue




              1. In Zotero, click on menu Help -> Check for update, install it and restart. That's it!

                • @ Tim Schumacher: thanks for the comments, but I think I will leave the update off. Zotero is running fine and, most importantly, this is not my own computer, otherwise I would assume the "risk".

                that makes sense. Do you know how I can run the Zotero updater with sudo?

                @BCArg Assuming the Updater fires up as soon as you launch zotero, it should be enough to run sudo su to open up a root shell and then just run zotero as a command line command to open it with root rights. Directly running sudo zotero is not recommended because it uses your real home directory and you may end up with root-owned files in your home directory.

                @ Tim Schumacher. Thanks for the reply. When I ran sudo su then zotero a message dialog with the following messaged popped-up: "you appear to be running Zotero as root. This is insecure and may prevent Zotero from functioning when launched from your user account. If you wish to install an automatic update, modify the Zotero program directory to be writeable by your user account.". Do you think it is safe to continue? Anyways, the updates are not that important for me by now.

                @BCArg The problem with changing the permissions for that directory (and all subdirectories and files) is that you probably won't be able to restore the original permissions on all files. As we changed the home directory to /root by running sudo su (instead of just running sudo zotero as the program seems to assume), it should all be fine if you continue and let it run the update.

                You'll want to also change the permissions of the /opt/zotero folder by running:



                sudo chmod 707 /usr/bin/zotero && sudo chmod -R 707 /opt/zotero

                        This depends on how (and where) did you install Zotero. I used the smathot/cogscinl repository to install mine (full installation instructions):



                        sudo apt-add-repository ppa:smathot/cogscinl


                        If this is your case, you will probably find your Zotero directory in /opt/zotero. You need to change the permission to the user that will update Zotero, basically this:



                        sudo chown USERNAME /opt/zotero
