Was working without issue within Ubuntu 18.04 on a dual-boot machine.
Installed a tex ide via the command line:
sudo apt-get install texmaker
which appeared to complete successfully. I subsequently clicked on the first gummi link in a response on this SE page, which lanched a new tab, appeared to be resolving, but never fully resolved after a minute or so. I closed it, launched a new tab and searched, never successfully getting to the page.
I wasn't doing much otherwise, just watching a youtube vid on an adjacent screen and realized my memory was blocked up after getting errors to cd via the command line. I tried a df on my home directory to see what might be causing it and showed most dirs with normal memory allocations, but a huge swapfile, multiple gigs. I tried restarting to clear it, but haven't been able to get back in.
I'd allocated 40GB for the Ubuntu partition, and don't save anything substantial there barring a couple GB movie files in the last couple days, without issue, so I wouldn't expect the recent install of texmaker would have changed things, even at 1GB+. Checking Windows disk manager shows 100% free, not sure whether that's good or bad (partition 5):
Any thoughts on how to diagnose and fix.
Edit (with additional boot detail): I'm able to boot, select Ubuntu from within the grub dialogue, and ultimately end up on a command-line looking screen with a version of:
/dev/p5 clean 234234/2342234 files, 234234/2324234 blocks
after which it hangs.
Edit 2:
I was able to boot into recovery mode and get to a terminal. fsck, dpkg, and clean all fail to resolve the issue. fsck aborts with '/dev/p5 is mounted, aborting' message.
I've included a picture of the error fsck returns as well as one of ll showing memory use (and the offending swapfile).
