After the upgrade from 18.10 to 19.04 I find the desktop useless. After logging in, I notice the following:
The Dash-to-Dock dock on the left does not show objects except the nine-point square (Task Drawer?). If you click on it, nothing happens.
If you move the mouse pointer to the upper left corner, the overview will not be displayed.
By clicking on the top left corner, I return to the login screen.
This works for all logins I've tried:
Gnomes on Xorg
Ubuntu on Xorg
I assume that a configuration item or a shell extension causes this. Before upgrading, I fully updated 18.10, but I installed shell extensions through extensions.gnome.org and did not think about checking for updates. (The software manager has indicated that the website with the Gnome shell extensions is not accessible.)
Does it have an advantage if I report this error before fixing it?
Finally, I will try to disable the shell extensions and the next configuration files. In the worst case I try XFCE and in the worst case Nuke and Repave.
What is the best way to report an error (considering I can not run GUI programs)?
If it does help, I've picked up a part of / var / log / syslog that might reflect the problem and dropped it at https://pastebin.com/UwdegT7Q. The salient line could be:
June 4 08:47:34 Karakum Gnome-Shell: Connection to xwayland interrupted
I am on Ubuntu 18.10 and Filezilla has caused me many problems. After the installation through the App Manager (outdated version), the shell (obsolete version) and the file .tar.bz2 of the website. I have found that only the file works.
But now I get one Error loading the queue and my credentials are not accepted (as with the outdated versions). I'm not sure what's up and troubleshooting will be frustrating, but at least I want to uninstall the version I got from the shell and see how well it works. The problem is that I do not know how. Any help?
I have Xubuntu 18.10 installed on my Chinese Windows tablet. But I have no sound. Alsamixer can detect my sound card (bytcr-rt5640), but pavucontrol does not show it.
I searched for it on the internet, the sound card worked, but after a few days it disappeared again.
How can I solve this problem?
Then I unzipped it to / home / kafka / kafka / and set the / etc / systemd files to zookeeper.service and kafka.service. If necessary, I can show you the content.
Then I tried to start with it
sudo systemctl start kafka
but something went wrong
Sudo journalctl -u kafka

However, I also tried to grant all users permissions to this folder with sudo chmod a + rwx and chmod -R 777 and 755. Nothing helps and this error still occurred.
I upgraded from Ubuntu 18.10 to 19.04 and then went for a few minutes to find something to eat …
When I got home, I realized that there was a power outage and my computer was in the middle of the upgrade. I did not know where he left off. So I cranked it up to see if it worked, and it worked well with the new version, but I could not figure out what was damaged because I did not know where the upgrade was going.
How can I check for corruption? Is there a tool for this or do I have to do something?
I get this error message when I try to update Ubuntu
Could not calculate the upgrade
There was an unsolvable problem calculating the upgrade.
This was probably caused by:
* Unofficial software packages that are not provided by Ubuntu
Please use the tool & # 39; ppa-purge & # 39; from the ppa-purge
Package for removing software from a launchpad PPA and
Try the upgrade again.
If this is not the case, please report this error with the command ubuntu-bug ubuntu-release-upgrader-core & # 39; in a terminal. If you want to check this yourself, check the log files in & # 39; / var / log / dist-upgrade & # 39; including upgrade details. Look in particular & # 39; main.log & # 39; and & # 39; apt.log & # 39; apt.log & # 39; on.
I have installed Power BI and PostgreSQL 11 on Windows 10 and my primary PostgreSQL 11 database on Ubuntu 18.10 Linux. I have correctly adapted the postgresql.conf and pg_hba.conf files to the IP addresses my Windows 10 computer uses with PostgreSQL 11 and Power BI to connect to my PostgreSQL 11 Ubuntu database. However, I have errors in Power BI while I was able to connect manually from the command line.
After troubleshooting Microsoft Support, I was told, "This indicates that the Postgresql server has not configured its certificates and therefore can not connect to PowerBI." For the client to verify the identity of the server, place a root certificate on the server Client and A leaf certificate signed by the root certificate on the server For the server to verify the identity of the client, place a root certificate on the server and a leaf certificate signed on the client by the root certificate One or more intermediate certificates (usually stored together with the sheet certificate). "
However, I am confused by the tutorials at https://www.postgresql.org/docs/current/libpq-ssl.html and https://www.gab.lc/articles/postgresql_with_ssl/.
I can not say what steps need to be performed on my Ubuntu PC and what steps need to be performed on my Windows PC. I do not know if special steps are required to configure Power BI with the certificates. How do I set up my bidirectional certificates?
Can someone offer a very detailed tutorial, tell me how to read a tutorial, or explain the steps in an answer?
