Не могу запустить браузер - Beaker, Falkon, Colibri

Не удается запустить браузеры Beaker, Falkon, Colibri с одним из пользователей. Другие пользователи работают нормально.

Я получаю следующую ошибку:

$ beaker-browser
system_key.go:129: cannot determine nfs usage in generateSystemKey: cannot parse /etc/fstab: expected between 3 and 6 fields, found 7

Я использую Ubuntu 18.04, а вот мой / etc / fstab :

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

# READ
# Ubuntu enables periodic TRIM by default no need discard option
# No options means = rw,relatime 
# Ubuntu defaults = rw, suid, dev, exec, auto, nouser, and async. Later options chanve defaults 
# relatime - updates file access info once a day (by default) or on file change. noatime - dont update
# nosuid - other users cant execute not their files
