flatbield

I use primarily debs but if your using Ubuntu it will include Ubuntu supported snaps. This is all from the distro supplied repos generally.

Installing random stuff not distro support contains a lot of addition risks such as potentially more bugs and malware.

I think the only 3rd party program I have installed is an AppImage of Joplin. I found the snap buggy.

I am not big fan of snaps or flatpacks as I had issues with both. One rarely needs them on Debian based distros anyway.

Just thinking what possibilities. Some thoughts.

• We always use Ubuntu LTS and do not install or upgrade a release until is out for 6 to 9 months. For Debian we use stable.

• Make certain your install media is good and also the computer storge media.

• Keep the system updates current.

• Use packages installed from the standard repo and supported by the security team.

Not sure what else.

Just FYI. My family has used linux for 25 years on many systems and we do not have stability issues. We use mostly Ubuntu or Debian.

Have no idea why your having issues. Could distro or hardware related. Also are you sure your storage media is good.
