How To:
Debug quota issues in UMC.
When opening the UMC module you might get an error about “Internal Server Error: The module process ended”
In /var/log/univention/management-console-module-quota.log you will see error messages like this:
17.01.20 10:31:20.793 MODULE ( ERROR ) : Traceback (most recent call last):

File "/usr/lib/pymodules/python2.7/univention/management/console/modules/quota/tools.py", line 320, in block2byte
size = long(size) * float(block_size)
ValueError: invalid literal for long() with base 10: ''
This is most likely a parse error from the command line to UMC as there might be an irregular value reported by the command line tool.
Troubleshooting
Start the repquota command as it does the UMC module:
/usr/sbin/repquota -C -v $PARTITION

The output should be similar to the above block.
You have to check the output in detail to see what is wrong with it. For some sort of automated check you might use the attached script from this bug.
For reference it is posted here, too:
import sys
from univention.management.console.modules.quota.tools import repquota_parse
# get the repquota report:
# /usr/sbin/repquota -C -v $PARTITION > quotareport.txt
# call this script with the path to quotareport.txt
# wait for a traceback... the last printed line is a problem
def main():
report_file = sys.argv[1]
with open(report_file, 'r') as report:
lines = report.readlines()
for line in lines[5:]:
try:
repquota_parse('foo', [line.strip()])
except ValueError:
print('############Broken?###########')
print(line.strip())
if __name__ == '__main__':
main()
