If a file-system *flips* from RW to RO, there will be a reason, and until you deal with that reason, you'll find it *flip* from RW to RO again & again so why not explore the problem now. You've not provided any OS/release details, plus *file-system* details which matter with these type of issues.

[Edit your question](https://askubuntu.com/posts/1447065/edit) and add the following: the distro and version of Linux, if dual boot with Windows, if dual boot, find out if fast boot is turned on in windows (this is the default) if the partition is in an external or internal drive, if external, if it was unplugged insanely, the type of filesystem, NTFS, exFat, ext4, etc.,

What is the mount point of `/dev/sda6`? Is it `/` or `/home`? If not, can you unmount the partition?

See [this question and all the answers](https://askubuntu.com/questions/59064/how-to-run-a-checkdisk) for how to check for problems in the drive.

Mounted on /, /var/snap/firefox/common/host-hunspell

Snap packages are RO and cannot be mounted RW intentionally (*so as to prevent corruption or malicious changes*). If a problem with a *snap* is found, you re-create the *snap* package to fix it. Snap mounts use no disk space (*they exist on the file-system and the `mount` you see for them just points to the existing copy*)

I Assume that you have mounted "/dev/sda6 /home ext4 defaults 0 0" in read only mode in fstab and now you want to mount it in read write mode then try mount -o remount,rw /home this will help for your.

@guiverc Ignore the `, /var/snap/...`. It's a side effect of snap bind-mounting the **host**-hunspell `/usr/share/hunspell` to there.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
