    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. – guiverc Dec 24 '22 at 05:47

    Edit your question 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., – user68186 Dec 24 '22 at 05:56
  • What is the mount point of /dev/sda6? Is it / or /home? If not, can you unmount the partition? – user68186 Dec 24 '22 at 06:08

    See this question and all the answers for how to check for problems in the drive. – user68186 Dec 24 '22 at 06:14
  • Mounted on /, /var/snap/firefox/common/host-hunspell – Sanket Babu Basnet Dec 24 '22 at 06:17
  • 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) – guiverc Dec 24 '22 at 06:29
  • @guiverc Ignore the , /var/snap/.... It's a side effect of snap bind-mounting the host-hunspell /usr/share/hunspell to there. – Martin Thornton Dec 25 '22 at 14:32
  • 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. – Badi Dec 24 '22 at 20:40
