I'm wondering if it could be related to https://sourceforge.net/p/libmtp/bugs/1797/. Newer Linux kernels require an updated udev rule which is only available with libmtp 1.1.16 (not in cosmic).

Randomly, copy/paste will stop and error reported. Status in libmtp package in Ubuntu: New Bug description: Steps to reproduce: 1) Plug phone into computer. 2) Copy a large number of directories with nested file structures to phone from computer hard drive, via Nautilus: [highlight files on computer, then ctrl-c; go to directory on phone, then ctrl-v]. Expected outcome: No copy errors. Actual Outcome: Usually, the expected outcome; randomly, Error: "Error while copying <filename>.m4a>. There was an error copying the file into mtp://LGE_LG-G710_LGG710PMd4...". Show more details : "File not found". Options: ["Cancel","Skip All","Skip"]. I can't force reproducibility, sometimes it won't complain, but larger copy/paste datasets correlate to more likely ending up with an error. Workarounds: At error, select 'Cancel'; delete the offending subdirectory/file from the phone; restart the copy-paste operation from the point of failure; repeat as necessary. lsb_release -rd: "Ubuntu 18.10" apt-cache policy nautilus: "nautilus: Installed: 1:3.26.4-0ubuntu7.1 Candidate: 1:3.26.4-0ubuntu7.1 Version table: *** 1:3.26.4-0ubuntu7.1 500 500 http://us.archive.ubuntu.com/ubuntu cosmic-updates/main amd64 Packages 100 /var/lib/dpkg/status 1:3.26.4-0ubuntu7 500 500 http://us.archive.ubuntu.com/ubuntu cosmic/main amd64 Packages" ProblemType: Bug DistroRelease: Ubuntu 18.10 Package: nautilus 1:3.26.4-0ubuntu7.1 ProcVersionSignature: Ubuntu 4.18.0-13.14-generic 4.18.17 Uname: Linux 4.18.0-13-generic x86_64 ApportVersion: 2.20.10-0ubuntu13.1 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Sat Jan 26 14:01:47 2019 ExecutablePath: /usr/bin/nautilus GsettingsChanges: b'org.gnome.nautilus.window-state' b'geometry' b"'890x550+67+30'" InstallationDate: Installed on 2019-01-10 (16 days ago) InstallationMedia: Ubuntu 18.10 "Cosmic Cuttlefish" - Release amd64 (20181017.3) ProcEnviron: SHELL=/bin/bash XDG_RUNTIME_DIR=<set> PATH=(custom, no user) LANG=en_US.UTF-8 SourcePackage: nautilus UpgradeStatus: No upgrade log present (probably fresh install) usr_lib_nautilus: To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libmtp/+bug/1813429/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
