Nemo Crashes during drag and drop and some other things

Sometimes when I drag and drop Nemo 4.0.6 crashes. I could put up with problems in less important apps if it happened (it doesn’t), but this is scary! I thought I had lost the files at first but they were there when I reloaded Nemo.

Does this also occur in Nautilus?

Please report this to launchpad with enough info so say how your can reproduce the problem.


In a terminal type:

ubuntu-bug nemo

Leave a link here once you have reported the issue.



If it gets looked at soon, I’ll stick with it so I can make information available if necessary. Otherwise I will have to revert to whatever version of Nemo was on 19.04 as I haven’t had problems with that before.

This is strange. Just tested in a clean install, doesn’t occur. Doesn’t occur on my system either. Can you try a live USB and see if the problem persists?

ok - I’ve knocked up a test PPA with some work that I did for Debian a while back. Please can you give it a test. If it resolves your issue I will push the fix officially into the repos - Canonical will ask you to retest via that bug report before it is allowed to be put into the release repos.


sudo add-apt-repository ppa:ubuntubudgie-dev/testnemo
sudo apt upgrade

Then logout/login.

Done, and I have copied a few files without problem, so I can stick with it for now. Obviously I can’t prove that the problem will never happen, I’ll just keep using it and let you know if it does.

Please try over the next few days. Let me know by close of the weekend.


Monday Morning: I haven’t done a lot of copying, but I haven’t had the problem again since using your PPA.

I have since found two more problems - I should probably start a new thread (and will do if you suggest it), but:

  • If I have the cursor highlighting a file, then change focus to another window, when I come back the file is still highlighted, but if I try to delete it - nothing happens, I have to select it again.

  • There’s another thing - something to do with a second pane, which I’ll put here if I remember what it was.

I’ve removed it and installed Nautilus. I’m struggling to compare/check files on several disks which is already doing my head in, I can’t handle any more complications :frowning:

Please can you test if you can reproduce the issue on the latest version of nemo on 20.04? i.e. download the latest daily - write it to a USB and boot into a live session. thx.

I’ve tried a couple of times and it’s OK.

Due to removing Nemo wrecking my system I have had to re-install UB. I then did add-apt-repository…–remove, upgrade, update. I am now on Nemo 4.0.6 which I assume is the standard version. That means I can test things on it for you and that I may also be reminded of the problem I couldn’t remember…

ok - please can you file a nemo bug report for the focus issue on launchpad - I need that to link the up-coming release of nemo with various patches.

Also please can you test the latest version of nemo in my test PPA - I need to check that I have identified the correct patch to resolve your focus issues.



Mouse Focus is not persistent

If I highlight a file then click on the other pane, then click back on the first pane, the original file is still highlighted, but if I then press [del] it isn’t deleted, because although it is highlighted, the file is no longer selected.

A similar thing happens if I stick to one pane, but it’s a bit difficult to explain, if I can think how to do so, I will post it here.

Since I have nearly finished what I have been doing, I’ll risk using two panes for a couple of days to see if I can spot the “problem I can’t remember”. I’ll use your test PPA version after that.
