manual configuration hp lj 1200 printer stuck on user password request

I tried to configure an HP lj 1200 printer on parallel port using the Gnome Printer configuration tool on ubuntu 19.04. After having manually chosen the appropriate model, driver and having clicked on ‘Apply’ I am asked for user and password. My user and password (sudo priviledges) do not work.

Any help is appreciated, thank you in advance.

User Profile Service Application Stuck in Provisioning

My User Profile Service Application (NOT the synchronisation Service) stopped working so I deleted and tried to recreate it using PowerShell.

I have tried a number of times – deleting it before I start again (and the Databases). Using the Central Administration deletion does not work so I use a mixture of STADM -o deleteconfigurationobject -Id {ID of USer Profile Service Application} and then a PowerShell script to delete the timer jobs. (PowerShell Remove-SPServiceApplication fails with a The SPPersistedObject with id, {Id}, could not be found.)

I have tried creating the User Profile Service Application using Central Administration and using PowerShell (running under the \SP_Farm account so the schema on SYncDB is correct).There are no CRITICAL or UNEXPECTED items in the Logs.

The last relevant item in the ULS logs is a message saying it is waiting for a timer job to finish.

“Waiting for service application instance provisioning job to complete for service application with name ‘User Profile Service’ and type ‘Microsoft.Office.Server.Administration.UserProfileApplication’ “

The SPTimer service is still running.

I am running SP2013 with the September 2016 CU.

What am I missing ?

Ubuntu 18.04 stuck on verbose screen on startup

I had done a sudo apt-get upgrade and was installing some packages(truffle,nodejs) when my laptop stopped responding and applications were not opening so I restarted it and when it booted it got stuck in the verbose boot screen and blinking intermittently.
All were showing [OK] so I pressed ALT + F2 and was able to login but it showed a few python value errors in file “/usr/lib/python3/dist-packages/lsb_release.py” ValueError: could not convert string to float: '6.06 LTS'
How can I fix this and complete the boot sequence please help?

CNN Predicting One Class and Accuracy Getting Stuck

My model is a binary classifier.

With the same exact architecture, the model sometimes gets high accuracies (90% etc), other times it predicts only one class (so accuracy is stuck at one number the whole time), and other times I get a loss value of “nan” (either too big or small that the loss value is not a number I’m guessing).

I’ve tried simplifying my architecture (down to 2 conv2D layers and 2 dense layers), seeding my kernel initializers with a random number (2), and changing the learning rate, but none of these actually solves the problem of inconsistency (they may help the model train to a high accuracy once, but if I run it again without changing any code, I get a very different result of either unchanging accuracy because it predicts only one class the whole time, or “nan” loss).

How can I fix this problem of: 1. Model having unchanging predictions for the whole run (predicting only one class the whole time). 2. Inconsistent and unreproducible results (when aforementioned issues come and go with no changes to the code) 3. Randomly getting “nan” loss values. (How can I get rid of them permanently?)

Thank you!!!!

Stuck at Removing Conflicting Operating System Files 14.04 to 16.04

I know this is a known bug and there are other posts about it such as Here However the posts don’t do me any good or skip a step or a hundred. First, they say to “Continue with the installation”. Huh I am stuck at:

enter image description here

I do not see a continue button??

I assume I need to hard reset the machine as nothing else is working, but these are important details missing in all workarounds I have found.

Some background: I have not used this machine for a while, I booted it up it was fine, but said that TeamViewer need to be updated (12). I tried the automatic update which did nothing so I found it online and tried installing. The progress bar froze for a few hours so I tried restarting. The restart also got hung after closing everything to I reset the machine. At boot I got nothing but a purple screen and recovery mode got stuck with a kernel panic. I attempted a boot repair which did not work. Then I tried booting from a 14.04.5 disk to try to reinstall. There was no re-install options. only in parallel or erase, or other. But here I got the “No Root File System Defined”, which is easy to look up and says all I need to do is set a partition to / Root, but no instructions on how to do it. I tried a 16.04.6 boot disk which gave me an update option so it could continue. This was hours ago and the picture shows what I have.

If I reboot, do I continue with the install, do an update or Other and what do I do. All the guides list some console commands, but I don’t have a console, just the update gui.

Sorry if am a pain, but I have been doing this for about 6 hours and am no closer to getting it working.

Thank you.

Complete Path is: /snap/nextcloud/current/htdocs/config/config.php Has anybody a tip how to change it into write permission? Thank you!
