      @Jpolk91 While George is pointing out the right configs to look at I think the issue is not about upload/download an image but only the error message initially posted about kernel update, right??

      So I’d suggest you follow @george1421’s advice on testing the FTP connection but instead of using /images you want to test this:

      cd /var/www/html/fog/service/ipxe
      mkdir backup
      put testfile.bin
      

      The last line simply means uploading a binary testfile.

      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

      Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

        Ugh, I needed to “read” what it said vs what normally is wrong. Thanks Sebastian for slapping me back to reality, its still 2019 right…

        There is/was a bug in FOG 1.4.4 where the permissions were not set correctly on /var/www/html/fog/service/ipxe to allow downloading of the kernels via the web gui. You could do this manually as root or sudo as root but not from the web gui. I would have thought a later fog installer script would have fixed that issue??

        Lets get the output on the ipxe directory using the same commands we used on /images:
        ls -la /var/www/html/fog/service
        ls -la /var/www/html/fog/service/ipxe

        We need to make sure that apache has write access into the ipxe directory for the web ui kernel updater to work correctly.

        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

          @george1421 @Sebastian-Roth I’m back, This one took forever to do and I was interrupted several times. one road block to be aware of having people do this in the future is windows FTP.EXE has a password character limit of 32 so if the auto-gen password is longer than that (mine is) it gets Truncated you can see this in action using FTP -d on windows and looking at the commands its actually sending, I don’t know what genius decided that was the limit but I can’t figure out how to get around it That being said…

          @george1421 FTP testing:
          I was able to get ftp’d into the fog server using Filezilla and can create and remove folders in both /images and /images/dev and then see the changes locally on the server. Here is the filezilla “log” history logged in as fogproject

          @Sebastian-Roth FTP testing
          I am able to access /var/www/html/fog/service/ipxe
          the backup directory already exists
          I am unable to create a file in that folder. from the filezilla log

          Status:    Logged in 
          
          Status:    Starting upload of C:\Users\[my windows profile]\Desktop\test.bin 
          
          Command:    CWD /var/www/fog/service/ipxe/backup 
          
          Response:    250 Directory successfully changed. 
          
          Command:    TYPE I 
          
          Response:    200 Switching to Binary mode. 
          
          Command:    PASV 
          
          Response:    227 Entering Passive Mode (10,104,1,104,252,158). 
          
          Command:    STOR test.bin 
          
          Response:    553 Could not create file. 
          
          Error:    Critical file transfer error 
          

          So i’m assuming it is a permission error somewhere in the ipxe folder, i’ll wait and let you guys tell me what to actually run so I don’t screw it up.

            Maybe I am blind but I can’t see directory backup here!! Later in your post you say “the backup directory already exists”?!

            CWD /var/www/fog/service/ipxe/backup

            Watch out /var/www/fog and /var/www/html/fog - one should be just a link to the other directory. Please run the following commands and post output here:

            ls -al /var/www/
            ls -al /var/www/html/
            

            Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

              “Watch out /var/www/fog and /var/www/html/fog”

              @Sebastian-Roth I was definately in /var/www/fog earlier (i must have missed the html part, sorry)
              its strange if they’re supposed to be a link though because I have
              “/var/www/fog/service/ipxe/backup”
              but
              “/var/www/html/fog/service/ipxe/backup” doesn’t exist
              Screenshot from 2020-01-03 13-49-07.png

                @Jpolk91 So it seems that you have a double install going on.

                Can you do:

                mv /var/www/fog/ /var/www/fog_old
                ln -s /var/www/html/fog /var/www/fog
                chown -R www-data:www-data /var/www/html/fog /var/www/fog
                chown -R fogproject:www-data /var/www/html/fog/service/ipxe
                chmod -R 777 /var/www/html/fog/service/ipxe
                

                Then retry the kernel update.

                Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                  @Tom-Elliott

                  1. yep, that did it. I’ve got 5.1.16 (NVME fix) installed which is what I wanted since this machine has a (i think) newer NVME drive and figured it may help, unfortunately my image is still hanging so all that and still work to do 😞 but no worries there I’ll go make another post on that in the appropriate forum if I can’t get it going! [Edit 3:45pm theres already a post re: elitebook 830g6! horray! gonna go dig there]

                  2. Is there anything else I may need to do or be aware of re: the double install or you think I should be good?

                  3. also I know it would be hard to guess with what we’ve shared and my assumption is I did something stupid without realizing it (I really need to find time to learn more about linux in general especially since I need to keep this server alive) but is there a “common” reason these issues may happen so I can avoid it in the future?

                  4. thanks so much to you @Sebastian-Roth and @george1421 you guys are all fantastic here! Absolutely top rate.

                    yep, that did it. I’ve got 5.1.16 (NVME fix) installed which is what I wanted since this machine has a (i think) newer NVME drive and figured it may help, unfortunately my image is still hanging so all that and still work to do 😞 but no worries there I’ll go make another post on that in the appropriate forum if I can’t get it going!

                    Yes please create a new post for this. There is a potential fix for this not related to the kernel. We do like to keep the problems and solutions to match the forum subject line so not to confuse future readers. The solution “depending on what the actual problem is” could be as simple as a kernel parameter change. Having pictures of errors will also help us understand the context of the error over just having the error message.

                    Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                      @Jpolk91 Great to hear this has fixed the issue for you!

                      Is there anything else I may need to do or be aware of re: the double install or you think I should be good?

                      Not that I know of from the top of my head. While I cannot promise you anything I would leave things as is and wait if any issue comes up.

                      At some point you might need to think about updating your Ubuntu install but 16.04 LTS is still fine at the moment. No rush.

                      also I know it would be hard to guess with what we’ve shared and my assumption is I did something stupid without realizing it (I really need to find time to learn more about linux in general especially since I need to keep this server alive) but is there a “common” reason these issues may happen so I can avoid it in the future?

                      I don’t think it is something you did. If I remember correctly there was an issue with this link in an older version. As you updated FOG from 1.4.x there is a chance that old version has messed it up. Sorry.

                      Learning Linux is a live long task. Even for me, working on Linux every day for many years. Just keep on playing with it and find yourself getting more and more comfortable. A great way is setting up a test environment in a VM where you can snapshot, test and re-install without much trouble…

                      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                      Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

                        Yeah thats definately on my to do list!

                        Yeah, I think I may try and work out of a VM every so often. Tried it before but the timing was unfortunate and I got literally buried at work so I never went back to it but it may be time to give it another go. thanks again for all you’re help! I’ll be back on Monday haha
