I had the same issue but due to multiple profiles. I guess the process for the transition to snap would not be able to tell whether there are other profiles or not, so I am not reopening. The solution: copy all existing profiles, like so:
cp -r ~/.google/someProfile1/ ~/snap/chromium/common/ cp -r ~/.google/someProfile2/ ~/snap/chromium/common/ Then you should be able to run them again: chromium-browser --user-data-dir=$HOME/snap/chromium/common/someProfile1 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1887396 Title: chromium-browser doesn't start Status in chromium-browser package in Ubuntu: Invalid Bug description: Upon launching chromium-browser from the terminal with the command: $ chromium-browser --user-data-dir=/home/albert/.config/google-chrome 2>&1 >> /dev/null I get this error: Gtk-Message: 15:31:01.011: Failed to load module "canberra-gtk-module" [5823:6010:0713/153101.029812:ERROR:disk_cache.cc(184)] Unable to create cache [5823:6010:0713/153101.029862:ERROR:shader_disk_cache.cc(606)] Shader Cache Creation failed: -2 [5823:5823:0713/153101.030904:ERROR:process_singleton_posix.cc(280)] Failed to create /home/albert/.config/google-chrome/SingletonLock: Permission denied (13) [5823:5823:0713/153101.030977:ERROR:chrome_browser_main.cc(1258)] Failed to create a ProcessSingleton for your profile directory. This means that running multiple instances would start multiple browser processes rather than opening a new window in the existing process. Aborting now to avoid profile corruption. ... and chromium remains closed. The chromium-browser and the command above worked fine until before the snap-ization of chromium-browser in Ubuntu 20.04, which came about yesterday when I run the updater.
