Running game on steam does not start MO2

[Cobra00747]

Today's error;

Yesterday I also got this error;

Fallout 4 is set up as instructions describe, all requirements fulfilled. Using POP!_os 22.04

Any suggestions would be greatly appreciated. Thank you for your time!

I'm running into the second error myself. Have you happened to have any luck with fixing this issue? I'm trying to get this working for Skyrim SE.

Update: One thing I tried was putting a symlink for steamapps in the skyrim folder (FO4 Folder for you) and it started to install but I ran into other issues after that.

No solution, all I did was attempt another install and I got the first error. Idk how that "fixed" the second error.

I found a fix for the first problem where mkdir can't make a folder in tmp. I opened up the install.sh file and changed the line (probably line 18) downloads_cache=/tmp/mo2-linux-installer-downloads-cache with the following line downloads_cache=/home/[user]/Downloads/tempcache/mo2-linux-installer-downloads-cache and it installed without issue. I did not run it as sudo, it found my game and installed MO2. However now it won't start up, so I have to troubleshoot that. But at least it installed.

Just as an aside, if it matters, I'm on Fedora 37 with Steam installed via flatpak.

edit 1: I created the folder tempcache in my Downloads folder and directed the install to go there.

edit 2: I fixed the second problem with it not starting. I installed MO2 in /home/[user]/.var/app/com.valvesoftware.Steam/.local/share/Steam/steamapps/common/Skyrim Special Edition/ But now for whatever reason it's telling me it can't start it. Will update when/if I can fix it.

edit 3: Ok, I figured this out. instead of pointing MO2 to the above directory, I created a folder in common named MO2 then pointed the install there, however, I had to set the install path with the default folder name. Once I did this, it asked me if I wanted to create the mod-organizer-2-skyrimspecialedition which I said yes to. MO2 then started up with no problems. If there are any issues with launching the game, I'll come back and add an edit. /home/[user]/.var/app/com.valvesoftware.Steam/.local/share/Steam/steamapps/common/MO2/mod-organizer-2-skyrimspecialedition/

edit 4: Since I'm using flatpaks, I'm having errors with MO2 handling nxm links. But there are guides on here to fix that.

edit 5: Threw out flatpak version of steam and protontricks. installed the native ones on fedora (can be done with other distros too, most if not all should have native versions) installed with similar methods above, put an MO2 folder in it's own folder in common, redirected the install to /home/[user]/.local/Steam/steamapps/common and now I can download mods directly in MO2.

I've modified line 18 with this downloads_cache=/media/cobra_007/External\ 1/tempcachedownloads Edited nothing else. I installed to home/cobra_007/Games/mod-organizer-2-fallout4 Got this error mkdir: cannot create directory ‘/media/cobra_007/External 1/SteamLibrary/steamapps/compatdata/377160/steamapps/compatdata/377160/pfx/drive_c/java’: No such file or directory After I get back from work I'll see what I can do to fix it.

I had to "babysit" the installation and make it's directory files manually. I got it fully installed however on running FO4, MO2 didn't start, instead it proceeded with startup of FO4. I don't know if there's any error files or not, but so far the installation is complete.

I'm getting the same mkdir error with Fallout New Vegas. Looks to be same root cause of having Steam Library situated outside of home directory. Manually creating the directories isn't working.I also have also tried manually exporting path variables, editing the scripts to 'hardcode' the paths to the directory, and the usual reinstall/upgrade to latest/etc. I'm not sure what can be done but each time the script fails it fails at the java line. Curious if anyone has found a workaround because I've hit a wall. Willing to test what I can.

I haven't found any other error in regards to directory errors. I just followed the filepath directly and fixed it. I'd make sure you made the file directory correctly without spelling errors or capitalization.

I also need to install MO2 for SSE and FONV so I'll do those soon and troubleshoot em, then report any errors here.

Alright, one day later and MO2 is installed on SSE and FONV. Neither of the two will start up. So, FO4, FONV, and SSE mod organizer 2 linux installs don't work properly; Installation is complete, but running the games on Steam doesn't start up MO2.

I'll let this sit now, I give up.

I'm also having the same issue with FNV where the install works fine, but neither the game nor the mod manager will start (I click "play", it turns to "stop" for a few seconds, and then reverts to "play"). I tried looking at Wine/Proton logs but couldn't find anything wrong (though I'm no expert). I'm using the flatpak verison of Steam.

Actually, following the above got it working for me

Inability to create the directory within /tmp is caused by broken permissions to the directory. Inability to create the java directory is caused by not creating a game prefix by running it on Steam when the installer instructs you to.
