In archlinux there is a patch for grsync to use gtk3. I used following steps to make binary package that's just works for me:
1. Download package from mirror to home directory: https://www.archlinux.org/packages/community/x86_64/grsync/ 2. Open up terminal make a new deb: mkdir archpkg tar xf grsync-1.2.6-4-x86_64.pkg.tar.xz -C archpkg/ apt download grsync mkdir edit dpkg-deb -R grsync_1.2.6-2_amd64.deb edit/ rm edit/DEBIAN/md5sums rm -r edit/usr/ mv archpkg/usr/ edit/ fakeroot dpkg-deb -b edit/ grsync.deb 3. Install new package with: sudo dpkg -i grsync.deb -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875947 Title: Grsync Starts Very Slowly In Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grsync/+bug/1875947/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
