edit: also tried sudo systemctl restart network-manager gave me as output: Failed to restart network-manage.service: Unit network-manage.service not found.
everything was fine before, but after I updated to Ubuntu 18.04.3 LTS just an hour or so ago my WiFi doesn’t find any networks anymore. I restarted my system several times and nothing changed.
here the output of ‘lspci -knn | grep Net -A3; rfkill list’

thanks for reading
- Did update BIOS (MB: Asus Z390-F)
- Did update NVMe SSD firmware (Samsung 970 EVO Plus, 500G)
- Did run
memtest86 for hours (after the problems happened: is OK)
- The MB (motherboard) has nothing else (no CD, no graphic card…)
Ubuntu install ( The SSD was supposed to be dedicated to Ubuntu 18.04 )
- Installed fresh Ubuntu 18.04.3
- Selected “Update while installing” + “Install 3rd party drivers…”
- Did manual partitioning, all ext4 (then tried also “Erase disk and install”)
- → Install had a “crash”, is “sorry” and “click to reboot”
So, tried again, the whole thing, without “Update while installing” & “Install 3rd party drivers…” (removed the network to be sure)
- this time it went through
- Then did
apt update ; apt upgrade
- Then after a while, using Ubuntu GUI, suddenly pages and pages of that
get displayed. Had to reset the PC.
My thoughts were for the NVMe SSD… but…
Windows 10 trial-install. So I installed Windows 10 (the free ISO) to confirm the problem is the SSD (Samsung supports only Windows)
- taking the whole disk,
- creating as many partitions as what was on Ubuntu
- did the MS updates
- did a stress test on all partitions, copying files over and over, filling the partitions
- rebooted many times
- → No errors anywhere, nothing in the s.m.a.r.t log (Samsung magician)
Therefore, it seems hard to blame the SSD.
Ubuntu 19.04 install. Then, on the data partitions created in Windows (except the one where Windows is) I installed Ubuntu 19.04 (not 18.04), thus these parts went from
- All went fine
apt update && apt upgrade
- Using Ubuntu,
- → then same as before, pages and pages of the same pic above
- → Reboot: goes to Grub “shell”
Booting (from BIOS) to Windows is OK. Ubuntu boot goes to grub shell.
Not sure what to do next …
- could be that the Ubuntu upgrade affects Grub (due to NVMe SSD)?
- could be a bad SSD, but in that case why Windows has no problem?
- both 18.04.3 and 19.04 use the kernel 5.0.x, could that be linked to the problem?
git remote -v shows the correct
upstream url’s but I wish I could just get the
(master) prompt back.
I reinstalled Ubuntu and installed Git.
I think the
(master) shows up for any new git repos but for ones carried over from the old Ubuntu installation on an external HDD don’t show
(master). Is there a quick solution?
I was trying to move all the files in a dir to another dir. I got errors at the first 2 attempts but at 3rd attempt it appeared the command did succeed. However the source dir is now empty but the files are not at the dest directory. Are they gone or is there a way I can recover them?
Here are the commands I executed (
Downloads is at
$ cd /DataVolume/shares/Public $ shopt -s dotglob $ mv -i Downloads/* /DataVolume/shares/Ricardo/Downloads mv: target `/DataVolume/shares/Ricardo/Downloads' is not a directory $ mv -i Downloads/* /DataVolume/shares/Ricardo/Downloads/ mv: target `/DataVolume/shares/Ricardo/Downloads/' is not a directory $ mv -i Downloads/* /DataVolume/shares/Ricardo/
After executing the last command I looked into
/DataVolume/shares/Ricardo/ but the files are not there. Then I went to look at
/DataVolume/shares/Public/Downloads and it’s now empty.
UPDATE If I execute the command
/DataVolume/shares/Ricardo/ i get this
$ ll /DataVolume/shares/Ricardo/ total 11252 drwxrwxr-x 5 root share 32768 Feb 13 2016 zzzzzz ADirectory drwxrwxr-x 2 root share 4096 Feb 12 2016 rrrrrr ADirectory -rw-rwxr-x 1 root share 5741378 Feb 12 2016 xxxxx.dmg drwxrwxrwx 15 www-data www-data 4096 May 16 2018 Documents drwxrwsr-x 8 ricardo share 4096 Feb 26 2017 DocumentsOld -rw-rwxr-x 1 root share 3514909 Feb 12 2016 yyyyyy.dmg drwxrwsr-x 7 ricardo share 4096 Jan 29 2016 OtherDir2 drwxrwxr-x 3 ricardo share 4096 May 16 2018 OtherDir drwxrwsr-x 2 ricardo share 4096 Sep 30 2015 Other Dir3 -rw-rwxr-x 1 root share 2188642 Feb 12 2016 zzzzz.tar.tar.gz
One thing I can notice is the datetime for
/DataVolume/shares/Ricardo/ is the same that the the datetime for
/DataVolume/shares/Ricardo$ ls -hal drwxrwx---+ 10 root share 4.0K Sep 22 09:23 . drwxrwxr-x 11 root share 4.0K Sep 22 09:06 .. ...

A returning net comes flying back into the hands of the creature that threw it, regardless of whether it hits or not. It’s easy to imagine the net flying back to its thrower when it misses. But once it has restrained its target, I can’t figure what happens. Does it bring back its taget?
While installing a new SSD to my Ubuntu server I have made the grave mistake of formatting a partition on the wrong drive. I’ve accidentally formatted the ESP partition of my HDD that contains the OS. This has lead to Ubuntu not booting at all anymore and the PC just telling me
reboot and select proper boot device.
I’ve googled all around, find posts telling me to use the Ubuntu Live usb and select “Rescue a broken system”, but those posts are all very old and neither the Ubuntu server nor normal image show me that option. I’m writing the images with Rufus as GPT so I’m able to boot the usb through UEFI. Another post mentioned selecting “reinstall ubuntu” after selecting “install ubuntu” but I don’t have that option.
I’ve tried boot repair both through Ubuntu live usb and as standalone live usb, but it returns 3 commands of which the last one fails. After I click continue it tells me grub is still present and to try again. I googled that too and they recommended editing the last command, but that didn’t work either.
Could someone point me in the right direction and tell me if this is even possible? It’s 5 am and I’ve been at this for 4 hours straight trying to get my server back up and running, hope my explanation is clear enough.
I had 18.04 and ran the built in graphical updater to upgrade to 19.04. When it restarted, I assumed I should boot into ubuntu as normal (multi OS system), but after doing so I get a loop of the screen flickering from off to black (backlit), to a single _ for a second and it just does that over and over. I can spam ctrl alt delete really fast and catch it in that 1 second it has a _ and it will restart, but I can’t get past this. Anyone know what is happening and how to fix it?

Fresh install, I go to Logitech to get app for my mouse. Popups for driver cleaners etc. Easy to find but one it seems loaded from common files to my services and secure like some are, as not to disable, right. Well I get the file name and nowhere is there a hint of it! ” ForeignHopeJKEye” This is the one that is an anomaly, It is an .exe type but can not figure its function, in my Services!
I have Win 10, UbuntuMate, and Deepin plus a partition called Data on my machine.
I recently upgraded Win 10 because it asked me to. Now I cannot access my Data drive with write permission on Linux OS’s on my machine.
To test whether anything I did was successful, I right click in Caja and see if I can create a folder.. NOPE..it is grey
I have tried:
shift + shutdown (Usually works for c-drive r+w problems)
Changing permissions to full control in Windows
Changing sharing to everyone in Windows
