I used Caja for the test NOT Thunar.

I cut and pasted using Caja, 44 files of 244 Mb from flash drive to hard drive.

No issues.

To be frank, I see no bugs ??

Since I did not see any problem, I did not update the package.

My system is running greatā€¦do not want to take a chance with that update.

Hi Ouroumov. I think it is an issue with the USB.

I installed and tested this with two other files different file managers - Thunar and PCManFM - and they both had the same problem. When copied one at a time, the files copied over, albeit a bit slowly. But, when copied as a batch, they got stuck. But did, eventually copy over. But it took many minutes.

When doing it via the terminal, it was a bit quicker, but not much

But, when copying the files, either via terminal or via any of the GUI file managers, from one folder on my internal hard drive to another, no problems were encountered.

Hey everyone! I'm the author of the update including these patches. Thanks for all the help testing!

I'm not sure any non-LTS distribution would still be affected by this issue unless they somehow overlooked upstream gvfs update releases

You're correct.

Please note that if it passes the verification, it will be released as a regular update through the Software Center. :slight_smile:

apologies for my ignorance to the process - but am I correct in assuming that if this fix is ā€œapprovedā€ through all the normal channels, then all I have to do is run ā€œsudo apt-get update && sudo apt-get dist-upgradeā€ on my Ubuntu MATE 16.04 machine to get the fix? I wonā€™t have to enable any non-standard repos?
HUGE thanks to everyone who invested time into thisā€¦ itā€™s been bugging me for a long long time now (pun intended)

You're correct. Update will roll out to every Ubuntu 16.04 user through the normal update channels.

What does sudo apt-get dist-upgrade do ?

ā€œupgradeā€, as you might expect, attempts to upgrade all of your existing programs.

ā€œdist-upgradeā€ also attempts to upgrade all of your existing programs. But, will make ā€œintelligentā€ decisions if there is a conflict between the upgrade of one program with another one. So, sometimes, with ā€œdist-upgradeā€ you may find that one of your programs has stopped working in order for another of your programs to be able to upgrade. Though, this is reasonably rare, from what I have read. And it has never actually happened to me.

And to be honest, if it was going to happen, I am the kind of user it would happen to since I have a relatively unusual combination of programs on my system

If youā€™re ever questioning, just do a man to read the manual.

man man
man apt

OS: Ubuntu Mate 17.04 with all the latest updates.
Issue: system locked (or in deep crawl).
Description:

  • installed Nemo
  • Commandline: gksudo nemo
  • began moving files & folders from one folder to another, over 1,000.

System unresponsive.

  • Ctrl+Alt+F1 - logged in
  • sudo htop

Noticed a series of applications using either 14.3% of processor power, or 13.6%. Combined set of applications pushing both processors to 100% usage:

  • mate-maximus
  • tilda
  • mate-session
  • mate-screensaver
  • caja
  • mate-panel
  • nm-applet
  • marco
  • mate-volume-control-applet
  • redshift
  • osmo

Noted too that the apps in this list would vary in their % and sometimes be dropped out of the high-usage list.

  • sudo service lightdm stop

System returns to my control, however the memory seems to be filled with a lot of residual data.

Hope this helps.

Iā€™ve installed the updates. On a samba share with ~16K jpegs from a security camera its still pretty slow, but it is improved!

On a local directory with ~24K jpeg files its much improved. Faster that gthumb loading the same directory.

Nice, It was frustrating on directories with a large number of images ā€“ as gets generated by motion or zoneMinder.
