Is it possible to use mark2 on ubuntu 20.04?

getting this error

I removed the line in mark2 properties that had to do with UseConcMarkSweepGC and got my server to startup up, but I'm getting this error now: https://pastebin.com/8K3fLXcr

Probably gonna need your Mark2 properties to resolve this

[Column01]

Try this: https://github.com/gsand/mark2/issues/64#issuecomment-269060176

You can probably omit all but the python-dev package

[Column01]

Seems python-dev didn't install or isn't installed correctly and it cannot get process info from the PID for the server. As for the first error, you likely configured the JVM arg you wanted incorrectly or are using a newer java version which doesn't support it

got this error when trying to install python-dev: https://pastebin.com/HUZ8mdwD

I tried running those commands, it installed everything, but still get the same error as posted above.

[Column01]

Does python -V print Python 2.7?

[Column01]

Also, you don't install python-dev, it's a ubuntu package so it needs to be installed with sudo apt-get install python-dev as you tried, just curious if python is using the wrong version with the python command

[goflishMC]

python -V

It say's, "Python 2.7.18"

I'm using Java 16 open jdk here's my mark2.properites: https://pastebin.com/R5KGJzbD

[Column01]

Java 16 doesn't support the JVM arg you are trying to use. Can you also try:

sudo apt-get autoremove python-dev
sudo apt-get install python-dev

[goflishMC]

Java 16 doesn't support the JVM arg you are trying to use. Can you also try:

sudo apt-get autoremove python-dev
sudo apt-get install python-dev

still get the same issue after doing that: https://i.imgur.com/Wgfw83t.png

[Column01]

Can you try:

sudo apt-get autoremove python-dev
sudo apt-get install python-dev-is-python2
sudo pip uninstall psutil
sudo python -m pip install psutil

[Column01]

if the last command doesn't work, just use sudo pip install psutil instead

[goflishMC]

Can you try:

sudo apt-get autoremove python-dev
sudo apt-get install python-dev-is-python2
sudo pip uninstall psutil
sudo python -m pip install psutil

still get this error when starting up the server: https://i.imgur.com/GzRLoxp.png

There has to be another underlying issue causing it, that try: except should only occur if the process doesn't exist AKA it crashed loading, regardless that is not a valid error to catch (it's really psutil.NoSuchProcess)

Do you mind editing a file locally to confirm it's not the issue?

Go to wherever you installed mark2 and edit the /mk2/services/process.py file and change psutil.error.NoSuchProcess to just psutil.NoSuchProcess on line 166

After making that change I get this: https://i.imgur.com/yohDYps.png

[Column01]

OK pretty sure I messed up and it installed new versions of psutil cause we didn't specify one compatible with mark2.

Try:

sudo pip uninstall psutil
sudo pip install psutil==0.6.1

[Column01]

and maybe also revert the changes I asked you to make lol

[Column01]

If for some reason it doesn't work, you should remove all mark2 dependencies and reinstall them.

See here which seems to be a related issue regarding installed dependencies.

I think that fixed it! I'm not getting the error anymore and it's showing my cpu and mem now in the console

Thanks for taking the time to help me with this!

[Column01]

No problem, sorry it took me so long to figure out that I forgot the version is very important haha

You can close this now if your issue is resolved

[Column01]

@goflishMC mind closing this? I don't have the perms to do it haha
